In pea plants, the allele for purple flower color is dominant to the allele for white flower color. if you were to perform a test cross to determine the genotype of a purple-flowered plant, what would you expect the phenotypic ratio of purple-flowered to white-flowered progeny to be if the plant is homozygous? and what would you expect if the plant is heterozygous?
a. if the purple-flowered plant is homozygous, then the progeny would all have purple flowers; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1: 1 ratio.
b. if the purple-flowered plant is homozygous, than the progeny would all have white flowers; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1: 1 ratio.
c. if the purple-flowered plant is homozygous, than the progeny would have purple to white flowers in a 1: 3 ratio; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1: 1 ratio.
d. if the purple-flowered plant is homozygous, than the progeny would all have purple flowers; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 3: 1 ratio.
e. if the purple-flowered plant is homozygous, than the progeny would have purple to white flowers in a 1: 3 ratio; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1: 3 ratio.
