Gametes Formation Based on Genotypes

1. Genotype AA BB: - The gametes formed will be AB only. This is due to the principle of independent assortment, where alleles of different genes segregate independently of one another during gamete formation.

2. Genotype Aa Bb: - The possible gametes formed will be AB, Ab, aB, and ab. This is also due to the principle of independent assortment, where alleles of different genes segregate independently of one another during gamete formation.

3. Genotype Aa BB: - The possible gametes formed will be AB and aB. This is due to the principle of independent assortment, where alleles of different genes segregate independently of one another during gamete formation.

4. Genotype AA Bb: - The possible gametes formed will be AB and Ab. This is due to the principle of independent assortment, where alleles of different genes segregate independently of one another during gamete formation.

Gametes Formation in Dihybrid Organism with Recessive Traits

In a dihybrid organism with recessive traits, the gametes formed will follow the principle of independent assortment. If the organism is homozygous recessive (aabb), the gametes formed will be ab only. This is because during gamete formation, alleles of different genes segregate independently of one another.

Gametes Formation in Heterozygous Organism

In a heterozygous organism, the gametes formed will follow the principle of independent assortment. For example, if the organism has the genotype Aa Bb, the possible gametes formed will be AB, Ab, aB, and ab. This is due to the independent assortment of alleles of different genes during gamete formation.
