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

I wish I could draw this. in all four quadrants you will see Aa. the entire plant has dominant genes. Again I wish I could draw it here but it wont let me sadly.

Answer 2

Let the genotype of parents for the axial position be represented as: AA

Let the genotype of parents for the terminal position be represented as: aa

Using Punnett Square rule to determine the genotype and phenotype of the offspring

Parents A  A

a Aa Aa

a Aa Aa

All the offspring have genotype as Aa in which axial position allele A is dominant.  So the axial position is dominant in offspring.
