Answer: The correct answer is option a. homozygous.
Alleles are the alternate forms of a particular gene. The alleles for a specific trait are placed at the same position or have the same locus in the homologous chromosome and govern the particular trait. If they are different, it results into a different expression of that trait. Homozygous alleles have the same allele on both members of homologous pair of chromosomes at same locus. The genotype of homozygous alleles is identical alleles of the gene for a particular trait. The individual can be homozygous dominant or homozygous recessive. Individuals homozygous for a trait are homozygotes. In other words, homozygous alleles are identical for the same characteristic.
