Asked by munnamgautam20 | 22nd Aug, 2018, 04:33: AM
- Homozygous: Individuals are said to be homozygous if they carry two identical copies of the gene affecting a given trait on two corresponding homologous chromosomes. E.g. A tall pea plant with genotype TT is said to be homozygous.
- Heterozygous: Individuals are said to be heterozygous when they have different alleles occupying the gene's position in each of the homologous chromosomes. E.g. A tall pea plant with genotype Tt is said to be heterozygous.
