The offspring that is shaded, exhibit the:

• Recessive trait because they exhibit a trait that neither parent has

• Dominant trait because they match one or both of their parents

• Recessive trait because they match one or both of their parents

• Dominant trait because they exhibit a trait that neither parent has

Cystic Fibrosis is a serious lung disease that is inherited through two recessive alleles (ff). A male that is a carrier and a female that is homozygous for not being affected by Cystic Fibrosis have children. What percent of the couple's children are likely to be affected by Cystic Fibrosis? Complete a punnett square to help you answer this question.

• 0%

• 25%

• 50%

• 100%

In fruit flies, they can either have wings or not have wings. A purebred winged fruit fly is crossed with a purebred non-winged fruit fly. All offspring have wings. Which best describes the alleles for this trait?

• No wings is dominant to having wings

• Having wings is dominant to not having wings

• The alleles are codominant

• The alleles have incomplete dominance

If H represents the unaffected allele and h represents the affected allele, what are the most likely genotypes of the parents in the pedigree? You may need to do a punnett square to help you

• Hh and HH

• hh and hh

• HH and HH

Green monsters are dominant to purple monsters.A biologist claims the recessive allele is now gone. Choose the correct response to this biologist. (Hint-you may want to do a Punnett square to help you answer this)

• Her claim is correct because none of the offspring are purple

• Her claim is not correct because the offspring still carry the recessive allele even though it doesn't show up

• Her claim is not correct because the offspring's phenotypes are half green, half purple

• Her claim is correct because green dominates purple, erasing the purple trait
