1. 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 Purple flowers and constricted pod x PPff What are the gametes for each parent? PF, PF, Pf, pf AND PF, PF Pf, pf Complete Punnett square= Dihybrid plant PF Pf pF Pf PPFf Pf PPFf PPff PPff pF PpFf PPFf Pf PPff PpFf PpFf Probability= (Dd) pf Ppff Ppff ppFF ppfF Ppff ppFf ppff Offspring # of offspring Offspring genotype with genotype phenotype X PPFf PPff PpFf Ppff |~|A||~ What is the phenotypic ratio (Purple, Full: Purple, Constricted: White, Full: White, Constricted? 8:8:0:0 What proportion of plants with purple flowers is heterozygous for both traits? II. 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: 0:00 (Ee) purple, full pod purple, constricted pod purple, full pod purple, constricted pod X (FF).
Name (Last, First): III. Given the following pedigree below, use Punnett squares for each of the following possibilities: a) X- linked dominant, b) X-linked recessive, c) Autosomal dominant and d) Autosomal recessive in order to determine what is the mode of transmission of this trait. Disease allele = XA, X², A or a depending on mode of transmission of the disease respectively. Unaffected X chromosome = X 11 III a) X-linked dominant 9 2 11x12 c) Autosomal dominant 11x12 2 *2 8 Ở *Homozygous unaffected/No carrier=Normal 8 b) X-linked recessive | 1 x 12 9 d) Autosomal recessive | 1 x 12 IV. III I gets married with an unaffected /no carrier woman. The couple had numerous children but the disease only appears in all the girl children. Based on this new information, what is the mode of transmission of this disease? Write down all the possible genotypes for the following individuals: 1112 111 112 113114111_ III 2 13 11 4
