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:
A) homozygous.
B) heterozygous.
C) monozygotic.
D) dizygotic.
Homozygous
Referring to two genes of one pair that are exactly the same in every letter of their code. Most gene pairs are homozygous.
Heterozygous
Referring to two genes of one pair that differ in some way. Typically one allele has only a few base pairs that differ from the other member of the pair.
Chromosomes
The structures within cells that contain DNA and carry genetic information.

Final Answer :
A
Explanation :
Homozygous means having the same alleles (versions of a gene) for a particular gene. If the code of the gene from one parent is exactly like the code on the same gene from the other parent, this means that the individual has two identical alleles for that gene, making them homozygous. Heterozygous individuals have two different alleles for a particular gene. Monozygotic and dizygotic refer to twins, and are not applicable to individual genes.
