A female with an aa bb cc dd genotype is crossed with a male with an Aa Bb Cc Dd genotype. What is the probability that an offspring is born with an Aa Bb Cc Dd genotype (assuming that all of these genes are unlinked)?

1) If the parents of the first generation are SS and ss, then the second generation (mating of first-generation) will be, (choose) a) all Ss b) 1/4 SS, 1/2 Ss, and 1/4 ss c) 1/2 Ss and 1/2 SS d) 1/2 ss and 1/2 Ss 2) In a cross of Tt x Tt, the percentage of offspring that will have the same genotype as the parents is   (choose)  a) 75% b) 25% c) 50% d)100%

Consider an individual with the AB/ab genotype, and assume that alleles of the A and B genes areunable to recombine during meiosis. If this individual is crossed with an individual who is homozygousrecessive at both genes (ab/ab), what is the expected phenotype ratio in the offspring?

A purpled-flower plant (WW) is crossed with a white-flowered plant (ww). The F1 generation offspring are crossed with each other (selfing). Which of the following is the correct genotype of the F2 generation? A)WW, Ww, Ww, ww B)ww, ww, WW, WW C)Ww, Ww, Ww, Ww D)WW, WW, ww, Ww
