17) in certain plants, tall is dominant to short. if a heterozygous plant is crossed with a homozygous tall plant, what is the probability that the offspring will be short?
a) 1
b) 1/2
c) 1/4
d) 1/6
e) 0

Let, "T" is dominant over "t"
Cross  between Heterozygous plant & homozygous tall plant will be:
TT × Tt = TT, TT, Tt, Tt

In each offspring, there is one "T" which is dominant so, all the offspring will be tall. Hence probability for short offspring will be zero

In short, Your Answer would be Option E

Hope this helps!
