BIO 340 Activity #3 Trihybrid crosses, probability, andpedigrees
BIO 340 Activity # 3: Trihybrid crosses, probability, and pedigrees (PAGE 1 of 2) Name (Last, First): I. In garden pea plants, purple flowers (P) are dominant to white flowers (p), and full pod shape (F) is dominant to constricted pod shape (f). If one dihybrid plant (PpFf) and a plant that is homozygous dominant for P and has a constricted pod shape are crossed, what are the potential genotypes and phenotypes that can be expected in the offspring? What is the genotype of the parents? PpFf What are the gametes for each parent? PF, Pf, pF, pf AND Pf, Pf, Pf, Pf Complete Punnett square= Dihybrid plant Purple flowers and constricted pod Pf PPFf PPff PpFf Probability= (Dd) pf Ppff X Ppff Created by Dr. Susan A. Holechek for BIO 340 (2022) X Offspring genotype (Ee) PPFf PPff PpFf Ppff PPff What is the phenotypic ratio (Purple, Full: Purple, Constricted: White, Full: White, Constricted? What proportion of plants with purple flowers is heterozygous for both traits? II. # of offspring with genotype What is the probability that the following pair of parents will produce the indicated offspring? DdEeFf x DdeeFF -> DdEeFf Punnett squares for each individual trait can help you with this: Offspring phenotype Purple F X (Ff)
