In Mendel’s experiments, peas had two shapes: round and wrinkled. The round shape was dominant to the wrinkled shape. There are two alleles controlling this trait: R and r. The R allele is dominant to the r allele. A heterozygous plant (i.e. it has two different types of alleles) with round seeds is allowed to self-fertilize. Which image shows the correct Punnett square for this monohybrid cross? (Make sure you look at the gametes AND the fertilization in the Punnett squares below.)

In Mendel’s experiments, peas had two shapes: round and wrinkled. The round shape was dominant to the wrinkled shape. There are two alleles controlling this trait: R and r. The R allele is dominant to the r allele. A heterozygous plant with round seeds is crossed to a homozygous plant (i.e. it has two of the same alleles) with wrinkled seeds. What percent of the offspring from this test cross do you expect to have wrinkled seeds?

Consider the following pedigree: The trait being followed in this pedigree shows dominant inheritance. Let’s call the two alleles controlling this trait B and b. What is the genotype of the male marked with a 1? [Bb] What is the genotype of the female marked with a 2? [bb] The male marked with a 1 and the female marked with a 2 have a daughter marked with a 3. Does she have the trait? [yes] If this couple (1 and 2) wants to have another child (?), what is the probability that this child will NOT inherit the disease?[half]

A diploid cell from a woman is shown below. Will this woman be healthy? [yes] Does she have a chromosomal abnormality? [Robertsonian] If this woman gets pregnant, is she at increased risk of miscarriage? [yes2] If this woman gets pregnant, is she at increased risk of having a baby with Down Syndrome? [yes3] Can this woman have a child with normal chromosomes? [yes4]
