Which is a correct statement about gametogenesis?

Biology
1 answer:
erica [24]3 years ago
7 0

<span><span>In gametogenesis, germinal cells multiply by mitosis and mature gametes are formed by meiosis.

</span>Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. </span>Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.<span>

Naddik [55]

  • The smooth muscle is one of the three types of muscle present in the human body and other animals.
  • The smooth muscle is called smooth because of its smooth appearance without any striations in its structure.
  • The smooth muscle is made of the spindle-shaped cells characterized by a single nucleus.
  • The smooth muscle cells are controlled by the autonomic nervous system and therefore is involuntary in its action.

In a large flock of 6520 sheep, 53 of them have yellow fat while the rest of the flock members have white fat. Yellow fat is inh
Natasha_Volkova [10]

Answer:

number of sheep with homozygous dominant white fat genotype = 5399

Explanation:

If p = frequency of dominant allele and q= frequency of recessive allele

According to Hardy-Weinberg equilibrium:

p + q =1 and p² + 2pq + q² = 1

where p² = frequency of homozygous dominant genotype

q²= frequency of homozygous recessive genotype

and 2pq= frequency of heterozygous genotype

Here,

q² = 53/6520= 0.0081

q = √0.0081 = 0.09

p = 1-q = 1-0.09= 0.91

So, p² = 0.91² = 0.8281

number of sheep with homozygous dominant white fat genotype= 0.8281*6520 = 5399
