Answer to Question #145011 in Genetics for Jannah

Question

You found morning glory plants in a field by your house with flowers that can have two different colors: dark purple (CPCP) or white (CWCW). You pollinate purple flowers with pollen from white flowers. When you grow the F1 progeny you get plants with only light purple flowers! (1) Name the inheritance pattern that likely led to these phenotypes. If you self-pollinate the F1 progeny, use a Punnett square to predict (2) the genotypic ratio and (3) phenotypic ratio for flower color in the F2 progeny.

Answer 1

1. This trait is inherited due to two alleles for a single gene, with the purple allele dominant to the white allele.
