Genetic Problems: 1. Flat tail(F) is dominant to fuzzy tail(f), and toothed (T) is dominant to toothless, (t). Give the phenotypic and genotypic results between two completely heterozygous parents. 2. If a yellow guinea pig is crossed with a white one, the offspring are cream colored. What is the simplest explanation for this result? If you crossed 2 cream-colored, what would you get? 3. In a certain animal, black fur, B, is dominant to white fur, b. Determine the expected genotypic ratios and phenotypic ratios resulting from crosses between. A. homozygous black X white B. two heterozygous blacks C. heterozygous black X white 4. If a mother and a father both have type AB, will they be able to have a child with type O blood? What other blood types if any would be possible from these parents. 5. In flowers, red flowers are dominant over white flowers. If a cross red flowers with white flower I notice all my F1 generation is all pink. So I think I will cross one of these pink flowers with a red flower. What will be the color of the offspring? Please construct a Punnett square and explain this event and the genotypic and phenotypic ratio. 6. Hemophilia is a sex-linked trait in humans. If the trait is recessive as well what would happen if a mother was a carrier for Hemophilia and the father doesn't have a trait. Once again use a Punnett square, explain what it means in terms of genotype and phenotype. 7. If creatures from outer space have purple hair (which is dominant) to orange hair (which is recessive), and horns which is dominant to no horns which is recessive. If I cross two heterozygotes for these two traits hair color and horns, what would a Punnett square look like for this cross? 8. If tongue rolling is dominant to non tongue rolling, if two tongue rollers have a nontongue roller what must the genotypes of these people be? Make a Punnett Square and show your genotypes and phenotypes for all 9. Tall pea plants are dominant to short pea plants what would be the results between a heterozygous tall and short pea plant? Show your Punnett Square and ratios.
