Bob met Sally at a dance. Bob is homozygous for his dimples, but Sally does not have dimples. Dimples (D) is dominant to not having dimples (d). Use a punnett square to determine the genotypic probabilities that could result from this cross?

• 100% Dd

• 50% DD, 50% Dd

• 100% Dimples

• 50% Dimples, 50% No Dimples

Having mid-digital hair on your fingers is a dominant trait (H). If a father is heterozygous for this trait and a mother is homozygous for mid-digital hair, what is the likelihood that their children will have mid-digital hair? Complete a punnett square to help you answer this question

• 50% chance of mid digital hair

• 25% chance of mid digital hair

• 75% chance of mid digital hair

• 100% chance of mid digital hair

A pair of fruit flies reproduces and has 1,000 offspring. All 1,000 offspring have the alleles Gg. What is the most likely genotype for each parent? You may want to draw a Punnett square to help you answer this.

• GG x gg

• GG x Gg

• Gg x Gg

• gg x Gg

Plants can be either fuzzy (F) or smooth (f). A male fuzzy plant is crossed with a female smooth plant. Which stated observation and conclusion is most likely correct? You may have to do punnett squares to figure this out.

• Observation: All offspring are fuzzy. Conclusion: The male has two recessive alleles (ff)

• Observation: Half the offspring are smooth. Conclusion: The male is heterozygous (Ff)

• Observation: All offspring are smooth. Conclusion: The male has two dominant alleles (FF)

• Observation: Most of the offspring are fuzzy. Conclusion: The male has two dominant alleles (FF)
