Dihybrid Punnett Square Practice Problems Directions: Answer the questions that follow in your science notebook. For a particular plant, the allele for tall (T) is dominant over the allele for short (t). For the same plant, the allele for colored flowers (G is dominant over white flowers (c). A farmer as shown in the Punnett Parent 1 TtC 2. For a particular rodent, black fur (B) is dominant over brown fur (b), and a long tail (L) is dominant over a short tail (). Create a Punnett square that shows the genotypes of all the possible offspring that could result from the breeding of two of the rodents that are us for both traits Genotype for the cross Key B- b. L- a. What ratio of genotypes would result? Show your work. b. What ratio of phemotypes would result? Show your work.
Dihybrid Punnett Square Practice Problems (continued) 3. For the same type of rodent as in question 2, consider a cross between a male hetero zygous for both black fur and a long tail, with a female homozygous for black fur and a short tail Genotype for the cross Key B- b- L- What ratio of genotypes would result? Show your work. a. b. What ratio of phenotypes might be produced? Show your work.
