Use a Punnett square to determine the genotypes and phenotyp
Use a Punnett square to determine the genotypes and phenotypes produced when a pea plant that is heterozygous for purple flowers (P) and heterozygous for smooth peas (S) is crossed with another pea plant that is heterozygous for purple flowers and homozygous for wrinkled peas (s). The other flower color is white (p). Be sure to include the number of individuals for each phenotype.
Solution
Answer:
PpSs x Ppss
Gametes for PpSs = PS, Ps, pS, ps
Gametes for Ppss = Ps, ps
