Detailed explanation-1: -a) GG b) gg c) Gg d) none of the above. The correct answer is C. A heterozygous genotype has two different alleles that are involved in expressing a trait.
Detailed explanation-2: -If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair. The relationship between the two alleles affects which traits are expressed.
Detailed explanation-3: -So, the correct answer is D “Tt".
Detailed explanation-4: -Since the plant with the green pods is heterozygous for the trait, its genotype must be Gg. The problem does not state whether the plant with yellow pods is homozygous or heterozygous.
Detailed explanation-5: -Answer and Explanation: The correct answer: Among the following genotypes the heterozygous genotypes are: 3. Aa and 4.
