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: -Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ.

Detailed explanation-4: -You either have two dominant alleles (homozygous dominant) or two recessive alleles (homozygous recessive).

Detailed explanation-5: -Homozygous and heterozygous are terms that are used to describe allele pairs. Individuals carrying two identical alleles (RR or rr) are known as homozygous. While individual organisms bearing different alleles (Rr) are known as heterozygous.
