In pea plants, the allele for smooth pods (S) is dominant over the alleles for constricted pods(s). Which of the following pairs of terms are correctly matched?

• Ss- phenotype; smooth pod- genotype

• ss- phenotype; constricted pod- genotype

• ss- genotype; constricted pod- phenotype

Which of the following are true of dominant and recessive alleles? (Pick 2)

• Phenotypes are only determined by recessive alleles.

• An individual can have both dominant and recessive alleles.

• When both alleles are present, the resulting phenotype is always an intermediate blend of the two traits.

• Recessive traits are expressed only if the dominant allele is absent.

True or False: Certain characters can be influenced by environmental factors as well as just genotype.

• True

• False

In snakes, being rude (R) is dominant to being respectful ®, and being sneaky (S) is dominant to being sincere (s). A female snake that is homozygous recessive for both r and s trait is mated with a male snake that is homozygous dominant for both (R and S). Both R and S traits assort independently from one another.
