Following the fusion of an egg cell and sperm cell, the resulting diploid cell divides by mitosis to create two new daughter cells. Each daughter cell contains pairs of chromosomes, with one set inherited from each parent.


Which of the following best describes the pairs of chromosomes that are present in each newly formed daughter cell?


Choose 1 answer:


A) The pairs are homologous chromosomes that have the same set of genes, but likely different variations of those genes.


B) The pairs are non-homologous chromosomes that contain different sets of genes.


C) The pairs are homologous chromosomes that have identical copies of every gene.

The pairs are homologous chromosomes that have the same set of genes, but likely different variations of those genes. The correct option is A.

What are homologous chromosomes?

Among a pair of chromosomes with the very same gene sequence, loci, chromosomal size, and centromere location is referred to as a homologous chromosome.

One paternal and one maternal chromosome make up a homologous pair. In humans, the nucleus of a somatic cell contains 46 chromosomes.

Homologous chromosomes differ from sister chromatids because they are not identical and do not emanates from the same organism.

Sister chromatids are identical, side-by-side duplicates of each other that form as a result of DNA replication.

Homologous chromosomes do not pair together during mitosis. Homologous chromosomes line up end-to-end in mitosis so that when the cells divide, each daughter cell receives a sister chromatid from both members of the homologous pair.

Thus, the correct option is A.
