Question

If a corn plant was heterozygous for kernel color and seed shape, what would be the genotype of the plant?

Answer 1

Answer:

The genotype of the plant will be PpSs and the phenotype will be purple colour and smooth shaped.

Explanation:

Considering the description in the question, we know that purple colour is dominant over the yellow colour and smooth shape is dominant over the wrinkled shape.

A homozygous trait can be described as a trait which arises due to the same alleles of a gene. A heterozygous trait arises when both the alleles of a gene are different. In such a case, one allele will be dominant over the other one and the phenotype of the dominant allele will be seen in the plant. As purple colour and smooth shape are dominant traits, hence they will be seen in the heterozygous plant.
