- A pea plant is heterozygous for both pod shape and color. I is the allele for dominant, inflated pod; i is the allele for recessive, constricted pod. G is the allele for dominant, green pod; g is the allele for recessive, yellow color characteristic. Suppose this plant is crossed with a homozygous pea with inflated, green pod, what will be the possible genotype of the offspring? Identify the: Parents’ genes?Parents’ traits?Genes (genotype)?Shape, color? (phenotype)?Genotypic ratio?Phenotypic ratio?In pea plants, yellow peas (Y) are dominant and green peas are recessive, smooth peas (S) are dominant and wrinkled peas are recessive. Create a Punnett square to show the cross of a homozygous recessive (for both) male and a heterozygous (for both) female. Give the probabilities of each genotype and phenotype.Cross a homozygous dominant round/green seeded plant with heterozygous round/yellow seeded plant . R-round r- wrinkled Y- yellow y- green What are the genotypes of parents? What percent will be round/yellow seeds? What are the possible phenotypes? What are the possible genotypes?
- In peas, the yellow allele is dominant over the green allele. A plant with yellow peas was crossed to a plant with green peas. The resulting plants were 50% yellow and 50% green. What is the genotype of the parents in this cross? G/g xg/g OG/G x G/g G/Gxg/g Og/g *g/g OG/g x G/gIf body-color B is dominant to green body color b what would the genotype be for a heterozygous individual be? Using the blue B and a green b body color from above create a Punit square that represents the offspring of two heterozygous parents? what is the probability that they will have a child with a green body-color If the child is green what is its genotype?
