Chapter 2, Problem 10CONQ
A cross is made between a pea plant that has constricted pods (a recessive trait; smooth is dominant) and is heterozygous for seed color (yellow is dominant to green) and a plant that is heterozygous for both pod texture and seed color. Construct a Punnett square that depicts this cross. What are the predicted outcomes of genotypes and

Show the cross between a heterozygous purple flowered pea plant and a white flowered pea plant.
What is the genotypic ratio of the above cross?
What is the phenotypic ratio of the above cross?
In pea plants, flower color is determined by one gene with two alleles, with the allele coding for purple flowers (P) being dominant to the allele coding for white flowers (p). If two purple-flowered offspring resulting from a cross between homozygous dominant and white-flowered parents are crossed, what percentage of the progeny are expected to have the dominant phenotype?
Many of the color varieties of summer squash are determined by two different interacting genes A and B: AA or Aa gives white colored squash, aaBB or aaBb gives yellow squash, and aabb produces green squash. A plant producing white squash is self-crossed. Three fourths of the offspring produces white squash; one fourth produces green squash. What is the genotype of the parent plant producing white squash?
