)consider a pea plant- it has a gene controlling seed color- yellow vs green; another gene controlling seed texture-smooth vs wrinkled. a true breeding smooth green plant is crossed to a true breeding wrinkled yellow. all the f1 progeny were smooth yellow. the f1 generations were self-fertilized. assume the two genes (seed color and seed texture) are very tightly linked. in the f2 what is the expected ratio of the phenotypes- smooth & yellow: smooth & green: wrinkled & yellow: wrinkled & green 9: 3: 3: 1 1: 0: 1: 0 b
