21. Brown eye color is dominant; blue is recessive. If a brown-eyed man marries a blue-eyed woman and they have a browneyed boy and a blue-eyed girl, we can safely conclude…
A. the man is not the true father. B. the man is heterozygous.
C. eye color is sex-linked. D. both parents are homozygous.
22. John has genotype NN. His genotype would best be described as:
23. When crossing a homozygous recessive with a heterozygote, what is the chance of getting an offspring with the
homozygous recessive phenotype?
24. Black fur in mice (B) is dominant to brown fur (b). Short tails (T) are dominant to long tails (t). What fraction of the
progeny of the cross BbTt X BBtt will have black fur and long tails?
25. In snapdragons, heterozygotes have pink flowers, whereas homozygotes have red or white flowers. When plants with
red flowers are crossed with plants with white flowers, what proportion of the offspring will have pink flowers?
26. Homozygous dominant guinea pigs are white. Homozygous recessive guinea pigs are black. Heterozygous guinea pigs are
spotted with both black and white. This is an example of…
27. In 1944 Charlie Chaplin was involved in a legal battle over the paternity of a child born to Joan Berry, a young starlet. The
baby was blood type B, the mother A, and Chaplin O. From what you know about the inheritance of blood types, could
Chaplin have been the father of the child? (At the time of the trial, blood group evidence was not admissible in
California courts. Charlie Chaplin was declared responsible for the child's support.)
28. Huntington's disease is caused by a dominant allele. If one of your parents has the disease, what is the probability that
you, too, will have the disease?
29. What term describes the physical traits of a person?
30. Why are there so many phenotypes in polygenic inheritance?
31. A man with type A blood mates with a female with type B blood. Without any other info, what are all possible blood
types of the offspring?
32. The idea that for any particular trait, the pair of alleles of each parent separate and only one allele from each parent
passes to an offspring is Mendel's principle of:
33. Consider the following pedigree. The most likely mode of inheritance is:
Autosomal recessive, Autosomal dominant, X-linked recessive, or X-linked dominant
34. This diagram shows a pedigree for a recessive genetic disorder. What is the genotype of individual 6?
35. Widow’s peak is an autosomal dominant condition. The pedigree given shows
a family in which shaded individuals have the condition. Explain the pedigree.
