NEET BIOLOGY

Detailed explanation-1: -A genotype that has two copies of the same allele, for example: GG or gg, is called homozygous.

Detailed explanation-2: -When fertilization occurs between these plants, the offspring receives two copies of the allele, one from each parent. In this case, all of the offspring would have two different alleles, Gg, one from each of its parents. An organism that has an identical pair of alleles for a trait is called homozygous.

Detailed explanation-3: -Now, a pea with t he genes GG will be green is color, gg is yellow, and Gg is green due to the dominant gene, G. The GG, Gg, and gg above are known as genotypes. They denote the specific genes for that trait. The colors, yellow and green, are known as the phenotype, or the physical appearance of that genotype.

Detailed explanation-4: -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.
