In a flowering plant, flower color is controlled by the R gene, and flower shape (either personate or pelvic) is controlled by the P gene. Both genes are autosomal and independently assort.

Based on the following information from two crosses:

Red, peloric X white, personate --> F1: all pink personate

Pink, personate X red, peloric --> F1: 1/4 red, personate

1/4 red, peloric

1/4 pink, personate

1/4 pink, peloric

a) what is the pattern of inheritance for the R and P genes?

b) what are the genotypes of the parents in the two crosses?
