Explanation:
Detailed explanation-1: -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-2: -Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ. Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism.
Detailed explanation-3: -Homozygous: Having two identical alleles for a trait.
