Practice Quiz1. Round-seeded pea was crossed to a wrinkle-seeded pea all the
offspring were round. Diagram the cross and predict the ratio of wrinkled to round offspring in the F2 generation.
2. A round-seeded pea is crossed to a wrinkle-seeded pea. Half the offspring are round and half are wrinkled. What are the genotypes of the parents, the round F1 offspring, and the wrinkled F1 offspring?
3. True-breeding yellow, round plants were crossed to true breeding green, wrinkled ones. All F1 offspring are yellow and round. What are the genotypes of the parents and the F1 offspring? What phenotypes, and in what proportions, do you expect in the F2 generation?
4. A red snapdragon is crossed to a white snapdragon and all the offspring are pink. This is an example of what genetic property?
Practice Quiz5. A woman homozygous for the A allele of the ABO blood
group marries a man who is homozygous for the B locus. What is the blood group phenotype of their child? This is an example of what genetic property?
6. What is the most likely mode of inheritance illustrated by this pedigree?
7. The combined probability of two or more mutually exclusive events occurring is the ________ of their individual probabilities.
8. The joint probability of both of two independent events occurring is the _________ of their individual probabilities.
