Explanation:
In fruit flies, long wings are a dominant trait (L) and short wings are a recessive trait (l). Two fruit flies that are heterozygous for the long wings trait mate. The cross produces 180 offspring. How many of the offspring are expected to have short wings?
Answer:
45
Explanation:
Both parents are hetero-zygous, so each has alleles Ll.
When Ll crosses with Ll, we have
LL 25%
Ll 50%
ll 25%
So out of 180 offspring, we expect about 25% to have short wings, or
25%*180 = 45

10 Which of the following are examples of natural selection?
SELECT ALL THAT APPLY
A Domesticated dog breeds
B Giraffes developing longer necks over time
A non-poisonous snake mimics a poisonous snake
D Breeding two racehorses that are fast and strong
E Genetically modified soybean
F Galapagos finches choosing mates with stronger and longer beaks
G Allowing only the cows that produce the most milk to reproduce
H Peppered moths choosing mates with darker colors
Answer:
B Giraffes developing longer necks over time
A non-poisonous snake mimics a poisonous snake
F Galapagos finches choosing mates with stronger and longer beaks
H Peppered moths choosing mates with darker colors
Explanation:
Hope this helps
The examples of natural selection are as follows:
Giraffes develop longer necks over time.A Non-poisonous snake mimics a poisonous snake.Galapagos finches choose mates with stronger and longer beaks.Peppered moths choose mates with darker colors.Thus, the correct options for this question are B, C, F, and H.
What is Natural selection?Natural selection may be defined as the methodology through which organisms that are better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. The concept of Natural selection was first proposed by Charles Darwin.
According to the question, due to the requirement of long necks in order to get food from longer trees, Giraffe develops longer necks. In order to protect themselves from predators, a non-poisonous snake mimics a poisonous snake.
On Galapagos island, if there were variations in the finches of the bird, they get a variety of food resources in order to get more nutrients and energy for survival and reproduction.
Therefore, the correct options for this question are B, C, F, and H.

Question:What does codominance mean in genetics?
1.Both alleles are dominant and are expressed.
2.Both alleles are recessive and are not expressed.
3.The alleles are neither dominant nor recessive.
4.Each allele is both dominant and recessive.
Option 1
that can give nice mixtures of colors in flowers, like alleles for white and red are expressed, and mixed to pink seen by the human eye
Codominance mean in genetics is the alleles that are neither dominant nor recessive. So, the correct option is (C).
What is Codominance?Codominance is a type of inheritance in which two alleles of the same gene are expressed differently to produce different types of traits in an individual.
It is a heterozygous condition in which both alleles at a single gene locus are fully expressed in the phenotype. These alleles showing an independent effect are called codominant alleles.
In codominance, neither phenotype is completely dominant nor recessive. For example, the ABO type of blood group.
The gene which control human ABO blood groups has three alleles, not just two:
[tex]I^A[/tex] and [tex]I^B[/tex]are not dominant over one another. These are dominant over [tex]I^O[/tex].
Thus, Codominance mean in genetics is the alleles that are neither dominant nor recessive. So, the correct option is (C).

Entre as consequencias decorrentes do aumento da temperatura dos mares e dos oceanos, podem ser citados o derretimento das calotas polares, a diminuição no nível de oxigênio presente neles e a morte de corais. Escolha um desses exemplos e explique a relação entre ele e o aquecimento de mares e de oceanos.
Answer:
Death of coral reefs occurs due to increasing the temperature of the ocean.
Explanation:
Death of coral reefs occurs due to increasing the temperature of the sea and ocean because warm water killed the algae attached to the surface of coral reefs which causes bleaching of coral reefs. This coral reefs provides habitat as well as food to thousands of animals present in the ocean ecosystem so the destruction of coral reefs causes death or migration of animals from that region.

What are two ways that meiosis contributes to genetic variation? How do these two ways lead to variation?
Answer:
During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.Hope this is fine for you!!oofjnbjnbujbujbjlnboubojbnl;nuoibuoj
