What are homologs and when did they separate?

Expert Solution
Step 1

Cell division is a process in which a cell splits into daughter cells. In the process of cell division, the chromatin present in the nucleus shrinks and forms a thread-like structure called the chromosomes. There are mainly two types of cell divisions: mitosis and meiosis. Mitosis occurs in somatic cells, and meiosis occurs in reproductive cells.

Step 2

Homologs or homologous chromosomes are the pair of chromosomes (one maternal and one paternal chromosome) that pair up with each other inside a cell during cell division. These pair of chromosome consists of similar length, centromere location, and gene position on the chromosome, however, homologous chromosomes may contain genes with different alleles.
