1. In peas, inflated pods (I) are dominant over constricted pods (i). A pea plant that is heterozygous for pod shape undergoes a recombination event that includes the pod shape locus. At which meiotid division (I or II) are the alleles for pod shape segregated from each other?
2. In a certain plant, purple flower color (P) is dominant over white (p). If two heterozygous plants are crossed, what is the probability that 6 out of 10 progeny plants will have purple flowers?
3. Colorblindness is an X-linked recessive disorder. Sally and Bert have normal vision but both of their fathers are colorblind. What is the probability that a son or daughter born to Bert and Sally will be colorblind? Figure out the probability for the son and daughter separately. You DO NOT need to figure the probability for a birth in which you do not know the child's sex in advance.
4. In a cross between organisms having genotypes of AaBbCc and AaBbcc, what proportion of the offspring would be expected to be aaB_Cc?
