Explanation:

El pelaje negro de los borregos se debe a un alelo recesivo n frente a su alelo N que determina el pelaje blanco. Si cruzamos un individuo homocigótico blanco con un homocigótico negro, ¿de qué color serán los descendientes de la primera generación filial? GENOTIPO-FENOTIPO

Answers

Answer: Los descendientes de la primera generación filial tendrán un genotipo Aa y un fenotipo color blanco.

Explanation:

Un gen es un segmento de ADN que codifica para una proteína. Para cada gen, hay distintas versiones, conocidos como alelos. Por ejemplo, el gen que codifica para el pelaje tiene los alelos para el color blanco y para el color negro. Considerando que los organismos diploides tienen dos copias de cada gen (dos alelos), un alelo dominante solo necesita una copia para expresarse. Mientras que un alelo recesivo, necesita dos copias.

En este ejemplo, el borrego homocigota blanco tiene un genotipo (conjunto de genes) de AA ya que el color blanco es dominante y al ser homocigota indica que ambos alelos son iguales. El borrego homocigota negro tiene un genotipo de aa ya que se necesitan dos alelos recesivos para mostrar ese fenotipo (características visibles).

Los borregos producen gametos, los cuales son células sexuales (espermatozoide u óvulo) haploides, es decir que solo poseen un alelo de cada gen. Entonces el borrego AA solo produce gametos con genotipo A, mientras que el borrego aa solo produce gametos con genotipo a. Estos gametos son los que se cruzan, es decir que la descendencia solo puede tener un genotipo Aa (con un alelo de cada padre)

El genotipo Aa posee un alelo dominante A (que codifica para el color blanco) que enmascara los efectos de el alelo recesivo a (que codificaría para el color negro) Entonces, los descendientes de la primera generación filial tendrán un genotipo Aa y un fenotipo color blanco.

A population of ground mice consist of 500 individuals. You are interested in the gene that codes for for a color and find out there are 580 dominant alleles in this population. What is the allele frequency for the dominant allele? What is the allele frequency for the recessive allele? (show your work)

Answers

Answer:

0,58

Explanation:

Mice are diploid (2n) organisms, which means that their cells contain two complete sets of homo-logous chromosomes (i.e., they have two copies of any given locus/gene). An allele can be defined as a variant of a gene, whereas diploid (2n) organisms have two alleles at each genetic locus, which are located on homo-logous chromosomes. In this case, we know that there are 580 dominant alleles in a population of 500 individuals, thereby the total number of alleles in this population is 1000 (2n >> 500 x 2 = 1000 alleles), and the frequency of the dominant allele is 0,58 (580/1000 = 0,58).

Which of the following did you include in your answer?

Answers

can you send a picture of it?

Read the following selection and answer the question. On a September day in 1999, people began to notice that Lake Jackson in the Panhandle region of northern Florida was shrinking. Within a few days, it was almost gone. A sinkhole had opened beneath the lake and drained it, along with all of its inhabitants including fish and alligators. As aquifers lose water, rock and soil layers can become weaker and less capable of supporting overlying layers of earth and any human structures built upon them. In such cases, the land surface above may subside, or sink. Sometimes subsidence can occur locally and suddenly in the form of sinkholes, which are areas where the ground gives way with little warning. Once the ground subsides, soil becomes compacted, losing the porosity that enabled it to hold water. Recharging a depleted aquifer may therefore become more difficult. Sinkholes occur when?

Answers

Answer:

Sinkholes occur when water from the groundwater has been removed in excess.

Explanation:

Sinkholes are empty spaces in the ground that occur due to the landslide of large volumes of land, creating craters of different sizes. This landslide takes with it everything that is on top of it, such as houses, animals, streets and even entire buildings. While these holes can occur due to engineering flaws, the most common reason is the excessive use of groundwater, which creates an empty space in the interior of the soil and causes the earth to sag.

Which choice BEST explains why each island in the Galapagos has unique kinds of iguanas?

A. Iguanas prefer a marine environment.

O B. Some iguanas are better swimmers than others.

O C. The species arrived on the islands in different ways.

OD. The species adapted to each island's unique habitat.

Answers

OD because they acquired adapted traits to better suit them in their environment

The statement that explains each island in the Galapagos has unique kinds of iguanas is that the species adapted to each island's unique habitat. The correct option is D.

What is adaptation?

Adaptation is defined in biology as a heritable behavioral, morphological, or physiological trait that has evolved through natural selection and maintains or increases an organism's fitness under a given set of environmental conditions.

To survive, all organisms must adapt to their surroundings. This entails adapting to the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space.

The marine iguana is the only lizard in the world that can live and forage at sea, and it is only found in the Galapagos Islands.

There are eleven very similar subspecies found on various islands, with Isabela and Fernandina having the most. The species adapted to the distinct habitats of each island.

Thus, the correct option is D.

how does natural selection impact the way a population adapts?

Answers

Answer:

The organisms with the more desirable traits will survive and pass on their genes.

Explanation:

"Natural selection" is pretty much "survival of the fittest." This means that the organisms who have a better chance of surviving and reproducing will control the way a species adapts. For example, there may be a mutation in a species of moths that make their wings more brown instead of yellow (just threw a random color out there). Well, the moths born with the mutation that turns their wings brown will likely live longer and be able to reproduce more because they can blend in with their environment better. So, as a result, their mutation can get passed on and the species will adapt to have more moths with brown wings.

Many of the D-amino acids found in nature have been discovered in bacterially produced peptides that have antibiotic properties. Bacteria secrete these peptides into their environments to kill competitor bacteria and thereby gain a selective advantage. Given your answer to part (a) of this question, what potential advantages might D-amino acids confer to a secreted peptide toxin

Answers

Answer: D-amino acids are less likely to be recognized by proteolytic enzymes thereby they are not degradated.

Explanation:

Peptides are a type of polymers formed by joining several amino acids by means of peptide bonds. They are responsible for a large number of important cellular functions for the organism. Amino acids are thus the monomers that make up peptides and consist of an amino group (-NH2) at one end of the molecule and a carboxyl group (-COOH) at the other end.

Antibiotics are chemical substances produced by a living being (although they can also be synthetic derivatives made in laboratories), which kill or prevent the growth of certain kinds of sensitive microorganisms and are generally drugs used in the treatment of bacterial infections.

All amino acids, except glycine, are stereoisomers which means that there are nonoverlapping mirror images of their structure. These are labeled L (left-handed) and D (right-handed) to distinguish mirror images. A mirror image, for example, compares a right foot with a left foot. They are similar, but not exactly the same, they are like mirror images of each other. However, we could not, for example, put a right shoe on a left foot and vice versa. The same analogy applies to stereoisomers, they are similar but not superimposable, which means that not all compounds will act in the same way in an L or D molecule. For some reason, the amino acids that make up the proteins in human bodies are all L-amino acids.

To distinguish an L-amino acid from a D-amino acid, we must look at the α-carbon, which has four substituents forming a tetrahedron. then we must identify the hydrogen bonded directly to this carbon. In this way they are numbered and following the numbering order, they are classified as L or D.

Bacteria that secrete D amino acids kill other bacteria in the environment that might compete with them for resources, because they have antibiotic properties. These D amino acids are not usually recognized by proteolytic enzymes in organisms that degrade peptides or proteins. So the amino acid remains in the environment fulfilling its function, which is an antibiotic function to fight against other bacteria. Peptide toxins also fulfill this function, however, if they are destroyed by proteases.
