Final answer:
The possible genotype combinations in the offspring of two parents with genotypes Aa and Bb can be determined using a Punnett square. The possible genotypes include AA, Aa, aa, BB, Bb, and bb.
Step-by-step explanation:
The possible genotype combinations in the offspring of two parents with genotypes Aa and Bb can be determined using a Punnett square. The Punnett square is a simple tool used by geneticists to predict the probability of offspring genotypes resulting from a cross between two individuals with known genotypes. In this case, the possible genotype combinations would be:
- AA - homozygous dominant
- Aa - heterozygous
- aa - homozygous recessive
- BB - homozygous dominant
- Bb - heterozygous
- bb - homozygous recessive
