Question

The first 22 chromosomes contain hundreds of genes in the same positions and sequence. If the code of the gene from one parent is exactly like the code on the same gene from the other parent, the gene pair is _____.

Answer 1

Homozygous.

Step-by-step explanation:

As the exercise describes, when the first 22 chromosomes contain hundreds of genes in the same positions and sequence. If the code of the gene from one parent is exactly like the code on the same gene from the other parent, the gene pair is called homozygous. This is a genetic condition in which an individual has inherited the same DNA sequence, for a particular gene, from both their biological parents, therefore, having two identical copies of a particular gene.
