Question

The Punnett square illustrates a cross for flower position in the pea plant. The phenotypes and genotypes of the parents have been given. The allele for axial position is dominant and represented by A. The allele for terminal flower position is recessive and represented by a. What is the genotype of the offspring?

Answer 1

The offspring genotype will be:

• 25% = AA (dominant homozygote)
• 50% = Aa (heterozygous)
• 25% = aa (recessive homozygote)

Step-by-step explanation:

Punnett's painting was created by an English geneticist named Reginald Punnett (1875-1967). The researcher's objective with the creation of this framework was to demonstrate the variety of possible genetic combinations at a given cross.

In relation to the punnet square shown in the question above, the offspring will have the genotype:

• 25% = AA (dominant homozygote)
• 50% = Aa (heterozygous)
• 25% = aa (recessive homozygote)
