NEET BIOLOGY

Detailed explanation-1: -The presence of two identical alleles at a particular gene locus. A homozygous genotype may include two normal alleles or two alleles that have the same variant.

Detailed explanation-2: -Homozygous means having identical alleles for the same trait. i.e having 2 copies of the dominant allele or 2 copies of the recessive allele. Example: TT for tallness and tt for dwarfs. TT is homozygous for dominant character/trait and tt is homozygous for recessive character/trait.

Detailed explanation-3: -An organism with two identical alleles is homozygous.

Detailed explanation-4: -Being homozygous for a particular gene means you inherited two identical versions. It’s the opposite of a heterozygous genotype, where the alleles are different. People who have recessive traits, like blue eyes or red hair, are always homozygous for that gene.
