Title: 4. You have two purple?flowered pea plants where purple is made by the P allele? Post by: smmcmahon35 on Sep 5, 2012 4. You have two purple?flowered pea plants where purple is made by the P allele
while white flowers are made by the p allele. P is dominant over p. When you cross these two plants you get a 3:1 ratio of purple:white flowered offspring. What are the genotypes of the parents?

Pp x Pp makes PP, Pp, Pp, pp which are purple, purple, purple, white phenotypically (3:1 purple:white) Title: 4. You have two purple?flowered pea plants where purple is made by the P allele? Post by: Miguel2233 on Sep 5, 2012 Most likely both parents are heterozygous, that is Pp. This type of cross (monohybrid) usually results in a 3:1 ratio (dominant to recessive) in the offspring in the F2 generation.
