Consider a population that is in Hardy–Weinberg equilibrium at a locus with two alleles, A and a, at frequencies of p and q, res
nasty-shy [4]

Answer:

B) 2pq

Explanation:

Hardy-Weinberg equilibrium refers to a model which explains the effect of evolution on the gene pool.

The model is based on the assumptions that if no evolutionary force like genetic drift, natural selection and many other will act on the population and therefore the gene pool  (gene frequency and the genotypic frequency) of a populations remains in equilibrium or constant throughout the generations.

The genotypic frequency in the model is calculated by  

P² =  genotype of a homozygous dominant trait

q² = genotype of a homozygous recessive trait

2pq = genotype of heterozygous trait.

Thus, P²+2pq+q²=1

In the given question, since the population is in equilibrium that is no evolutionary force is acting, therefore, the genotype frequency remains the same that is the frequency of Aa will remain same that is 2pq even after 100 generations.

Thus, Option-B is the correct answer.

If the diploid number in a liver cell is 52, how many chromosomes are there is the egg of this organism?
allsm [11]
Gametes or sex cells (sperm and eggs) contain half the number of chromosomes that exist in autosomal cells; they are haploid. Therefore in the case where the diploid number of chromosomes is 52, the haploid number would be half of that, meaning 52/2 = 26.
