Athird-grader decided to breed guinea pigs for her school science project. she went to a pet store and bought a male with smooth black fur and a female with rough white fur. she wanted to study the inheritance of those features and was sorry to see that the first litter of eight contained only rough black animals. to her disappointment, the second litter from those same parents contained seven rough black animals. soon the first litter had begun to produce f2 offspring, and they showed a variety of coat types. before long, the child had 125 f2 guinea pigs. eight of them had smooth white coats, 25 had smooth black coats, 23 were rough and white, and 69 were rough and black. a. how are the coat color and texture characteristics inherited? what evidence supports your conclusions? b. what phenotypes and proportions of offspring should the girl expect if she mates one of the smooth white f2 females to an f1 male?

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
