Answer:
Answer: The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.

Daughter cells are the product of mitosis
The question is incomplete. The complete question is as following:
Tay Sach's disease is a fatal genetic condition, in which affected individuals cannot metabolize fats properly. Children who inherit the disease rarely live past the age of five. The disease is caused by the presence of a homozygous recessive gene. If a child has Tay Sach's disease, what would her parents' genotypes be?
Answer:
Parents will have heterozygous genotypes
Explanation:
Tay Sach is an inherited genetic disorder that destroys nerve cells in the spinal cord and brain.
Children with Tay Sach diseases have a homozygous recessive gene, it means both parents would have heterozygous because they carry heterozygous for the dominant trait. If any one from the parent would have homozygous recessive gene, they would have died as children. it means there are 25% chance that their child will inherit Tay Sach's.
Hence, the parents would have heterozygous genotype.
Four (4) spermatids result from one spermatogonium. Details about spermatogenesis can be found below.
<h3>What is spermatogenesis?</h3>
Spermatogenesis is the process by which sperm cells are produced from the testes of a male animal.
Spermatogenesis involves series of mitotic and meiotic divisions that finally result into the haploid sperm cells.
Spermatids are haploid cells produced by meiosis of a spermatocyte that develops into a spermatozoon.
The spermatogonium divides mitotically into primary spermatocyte which then develops into secondary spermatocyte via meiosis. Each secondary spermatocyte forms 4 spermatids.
