If you cross a Heterozygous Purple (dominant) flower mates with Homozygous White (recessive) flower, what is the genotypic ratio?

During gamete formation, the segregation of the alleles of one allelic pair is independent of the segregation of the alleles of another allelic pair

• Principle of Dominance

• Principle of Segregation

• Principle of Independent Assortment

RR = red

rr = white

Rr = red (complete dominance)

Rr = pink (incomplete dominance)

Rr = red and white (___________)
