1. As the new technician in a lab that studies coat color in rodents, you are assigned the task of counting and recording the coat color of the F2 progeny of a dihybrid cross. Your results are: 18 agouti mice, 6 black mice, 8 albino mice. Based on this data, you conclude that coat color in rodents
a. involves an epistatic interaction.
b. is determined by three different genes.
c. depends on prenatal nutrition.
d. involves incomplete dominance.
2. Why would a genetic counselor need to know how to construct a human pedigree?
a. A genetic counselor provides individuals and potential parents with the probabilities of inheriting a particular disease. An accurate pedigree is an essential part of establishing the correct probabilities.
b. A genetic counselor provides individuals and potential parents with the probabilities of inheriting a particular disease. An accurate pedigree is not necessary in determining disease.
c. A genetic counselor needs to know how to construct pedigrees to determine genotypes.
3. A genetic _____ contains the distances between the gene loci measured in terms of the frequency of recombination.
a. map
b. profile
c. construct
d. clone
