Question

In corn kernels, the traits for purple color (P) and plump kernles (S) are.dominant and the traits for yellow color (p) and shrunlen kernels (s) are recessive. a cross is made between a homozygous dominant for purple and plump kernels and homozygous recessive for yellow and shrunken kernels. What is the genotype and phenotype of each parent? Draw the Punnet squate for this dihybrid cross. Describe the genotype of all of the offspring. Describe the phenotype of all of the offspring​

Answer 1

Answer:

              ps        ps             ps                ps

PS    PpSs         PpSs        PpSs           PpSs  

PS    PpSs         PpSs        PpSs           PpSs  

PS    PpSs         PpSs        PpSs           PpSs  

PS    PpSs          PpSs       PpSs           PpSs  

The genotype of the dominant parent will be PS it will be homozygous dominant for purple colour and plump kernels. The phenotype will be purple colour and plump kernels.

The genotype of the recessive parent will be ps, it well be homozygous recessive for yellow colour and shrunken kernels. The phenotype will be yellow kernels and shrunken kenels.

All of the offsprings will have the genotype PpSs. They will be heterozygous for purple colour and plump kernels. The phenotype will be purple colour and plump kernels.
