Question

Name Population Genetics Homework- Due in Class Thursday, Jan. 29 versus green stems (alleles are P and p with P being completely dominant and coding for purple stems) and two alleles of a separate independent locus determine the 1. In tomatoes, two alleles of one locus determine the character difference of purple compicte d dtomenen or eur' yersus rotato" leaves (alleles are C and e with C being completely dominant and coding for cut leaves). You cross an individual that is PpCe with an individual that is homozygous recessive at both loci. a. Determine the expected phenotypic and genotypic ratios, assuming independent assortment (genes are unlinked)? Please show your work. The following progeny genotypes and phenotypes were observed: 25 PpCc (Purple, Cut), 25 ppcc (Green, Potato), 225 Ppcc (Purple, Potato), 225 ppCc (Green, Cut). Does this fit your expectation for phenotypic ratios if the genes are assorting independently? If not, what could explain this result? If the genes are linked, what is the arrangement of the genes on a particular chromosome for the double heterozygote?
