construct a genetic map using the three-point cross.
The shape of a pumpkin is determined by the action of two genes A and B. The recessive forms of these two alleles produces a flattened-shaped fruit, whereas the dominant forms of these two alleles produce the typical pumpkin with ridges. When both alleles are heterozygous a disc-shaped pumpkin is produced. If the genotype of the pumpkin plant is homozygous dominant at one allele and heterozygous at the other, the pumpkin will be ball-shaped. If the pumpkin plant is homozygous recessive at one allele and heterozygous at the other allele it produces an oblong-shaped fruit. Plants with genotypes other than the ones listed in this question do not produce pumpkins. Do the following cross: two pumpkin plants capable of making disc-shaped pumpkins are crossed with each other. Based on this cross, answer the following: (Show your work below.)

Let us suppose that two plants are crossed (mated). One plant (female) is homozygous dominant
and produces chlorophyll, and the other (male) is homozygous recessive and does not produce
chlorophyll. These two plants are considered the parental, or P generation.
What would be the possible genotypes and phenotypes of these two individuals? Fill in the
table below with the parental generation's descriptional information.
