What is formed from glucose during anaerobic cell respiration?
Explanation:
Glycolysis breaks down glucose (6-C) into two molecules of pyruvate (3C), and also produces: Hydrogen carriers (NADH) from an oxidised precursor (NAD+) A small yield of ATP (net gain of 2 molecules)
Suppose there were many chloroplasts in the cells of the upper epidermis. How would that change the amount of sunlight reaching the chloroplasts in the palisade layer?
Suppose there were many chloroplasts in the cells of the upper epidermis. The change the amount of sunlight reaching the chloroplasts in the palisade layer is that: The palisade mesophyll chloroplasts would receive less light if the top epidermis contained chloroplasts since they would absorb the majority of the sun's energy.
Do chloroplasts exist in the top epidermis?A single layer of cells, with few or no chloroplasts, makes up this layer. Since the cells are relatively transparent, most of the light that reaches them can reach the cells below. A waxy, waterproof cuticle covers the upper surface of the leaf, preventing water loss from the leaf.
Therefore, Palisade cells are the ones with the most chloroplasts per cell, making them the main location of photosynthesis in the leaves of plants that have them. Photosynthesis is the process by which light energy is transformed into the chemical energy of carbohydrates.

What happens to chromosomes during reproduction?
Meiosis, the second sort of cell division, makes sure that each generation of people has the same number of chromosomes. To create sperm and egg cells, a two-step process that cuts the number of chromosomes in half (from 46 to 23) is used.
Mitosis and meiosis are the two distinct processes of cell division. When people talk about "cell division," they typically mean mitosis, which is the process of creating new cells for the body. The cell division process known as meiosis is what produces egg and sperm cells.
A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each step of mitosis. Health issues like cancer may develop when mitosis is improperly controlled.

how to know if you carry the red hair gene
The test will examine each parent's DNA for evidence of the MC1R gene, which causes redheadedness. "We can... detect if an individual is a carrier of any of the three prevalent redhead variations in the gene MC1R using a simple saliva test to determine deep ancestry," stated Dr.
What causes red hair?
Red hair is a recessive hereditary feature induced by a sequence of mutations in the MC1R gene on chromosome 16. Because red hair is a recessive feature, it must be inherited from both parents.
As a result, there are significantly more persons harboring the red hair mutation than have red hair. Redheads account for around 13% of the Scottish population, with 40% carrying at least one mutation.

what is the definition of epistasis 1 point
The state known as "epistasis" occurs when the expression of one or more additional genes alters (e.g., masks, inhibits, or suppresses) the expression of a specific gene.
Epistasis refers to the interaction of genes that influences a phenotype. One phenotype with different properties can be determined by a conditional relationship between two genes. Genes can either work together to form a new trait or can hide one another so that only one is identified as "dominant." When it comes to gene pathways, this is typically seen since the presence or absence of one gene product directly impacts the expression of another gene within the pathway. This is also known as allelic complementation or interallelic complementation.
So, the interaction of genes with phenotype is what we mean when we say "epistasis."

What is the correct order of steps in the cell cycle ?
The cell cycle is a four stage procedure
Gap 1, or G1 phase Synthesis, or S phase Gap 2, or G2 phase Mitosis, or M phaseThe period between cell divisions is represented by the stages G1, S, and G2, which together make up interphase. An individual cell "decides" whether or not to join the cell cycle and divide based on the stimulatory and inhibitory signals it receives.
Checkpoint signalling systems and specialised proteins are used by cells to guarantee correct cell cycle progression. DNA damage is checked for before and after S phase at checkpoints at the end of G1 and the start of G2. Similar to this, a checkpoint in mitosis makes sure that the chromosomes are properly separated in anaphase before the cell's spindle fibers are properly aligned in metaphase.
Hence, cell cycle is sequence of event in organized manner.

What is distribution of traits?
The alleles of the various genes that each individual chromosome carries are mixed and matched traits with regard to one another, resulting in a distribution of traits.
When comparing populations, differences are typically seen as variations in the frequency distributions of the states (or kinds) of a certain feature (or set of traits). As a result, if two or more populations exhibit the same trait states at the same rates, they are said to be identical. A population's variance and pattern of attributes are influenced by both genetic and environmental variables. During meiosis, chromosomes can switch sections, causing mutations brought on by environmental factors, mistakes in DNA replication, or both.
As a result, we can infer that the alleles of the numerous genes that each chromosome carries are mixed and matched traits in relation to one another, producing a distribution of traits.

Answer:
Latent Disease
Explanation:
Causative agent remains inactive for a. time, but then becomes active and produces disease symptoms.
Imagine you are a genetic counselor and a couple (Martin and Shelley) comes to you for information. Martin has a sibling with sickle cell anemia, but neither he nor his parents have the disease. Shelley was married once before and did have a male child with sickle cell anemia. She does not have the disease herself. (sickle cell anemia is an autosomal, recessive disease)
What is the probability that their unborn baby will have sickle cell anemia?
The probability that their unborn baby will have sickle cell anemia is 1/4 or 25%.
Genetic probabilitySickle cell is an autosomal recessive disease. This means that both males and females have an equal chance of having the disease. They can also be carriers or not affected equally.
Martin does not have the disease but has a sibling with sickle cell anemia. It means his parents are each a carrier of the disease. Assuming the allele for sickle cell is s.
Ss x Ss
SS Ss Ss ss
Probability of unaffected = 1/4
Probability of being a carrier = 1/2
Probability of being affected = 1/4
Shelley was once married and had a male child with sickle cell. Since she does not have the disease herself, it means she's a carrier (Ss).
Assuming Martin is unaffected:
SS x Ss
SS Ss SS Ss
Probability of their unborn having sickle cell = 0
Assuming Martin is a carrier:
Ss x Ss
SS Ss Ss ss
The probability of their unborn having sickle cell = 1/4
Thus, the probability that their unborn baby will have sickle cell anemia is either 0 or 25%
P(A or B) = P(A) + P(B) - P(A and B)
