Suppose that in plants,smooth seeds (S)are dominant to wrinkled seeds (s)and tall plants (T)are dominant to short plants (t).A tall plant with smooth seeds was backcrossed to a parent that was short and wrinkled.Assuming independent assortment,what proportion of the progeny is expected to be homozygous for short and wrinkled?
A) 1/2
B) 1/4
C) 1/8
D) 1/16
E) 0

Quizplus · Accepted Answer

The tall plant with smooth seeds is heterozygous (SsTt) and the short, wrinkled parent is homozygous recessive (sstt). The progeny will be 1/4 homozygous short and wrinkled (sstt) due to independent assortment.
