The allele for the smooth shape of pods (I) is dominant over the allele for the constricted shape of pods (i) and the allele for the green color of pods (G) is dominant over the allele for the yellow color of pods (g). A pure breeding female parental pea plant with smooth green pods is cross-fertilized with a pure breeding parental male pea plant with constricted yellow pods. The resulting F1 generation plants are then self-fertilized and F2 generation progeny are obtained. The distribution of the appearance or phenotypes of the pods of the F2 generation plants are ______.
Pea plants have pods that are smooth (inflated) or constricted in shape and green or yellow in
color. These two autosomal traits observe the laws of
independently of one another. One gene affects pod shape and one gene affects pod color. The
allele for the smooth shape of pods (I) is dominant over the allele for the constricted shape of
pods (i) and the allele for the green color of pods (G) is dominant over the allele for the yellow
color of pods (g).
A pure breeding female parental pea plant with smooth green pods is cross-fertilized with a pure
breeding parental male pea plant with constricted yellow pods. The resulting F1 generation
plants are then self-fertilized and F2 generation progeny are obtained.
The distribution of the appearance or
______.
a- 100% smooth green pods
b- 100% constricted yellow pods
c- 50% smooth green pods, 50% constricted yellow pods, 0% smooth yellow pods, 0%
constricted green pods
d- 25% smooth green pods, 25% constricted yellow pods, 25% smooth yellow pods, 25%
constricted green pods
e- 56.25% smooth green pods, 6.25% constricted yellow pods, 18.75% smooth yellow pods,
18.75% constricted green pods
