In the Punnett square shown, which of the following is true about the offspring resulting from the cross?
T = tall
t= short
The partial Punnett square shows a cross between two tall pea plants. The allele for tall height
a
all offspring will be homozygous tall
b
all offspring will be short
c
all offspring will be heterozygous short
d
all offspring will be tall
The correct answer is: d) all offspring will be tall.
In the given Punnett square, since both parents are tall (homozygous dominant), they can only pass on the allele for tall height (T) to their offspring. Therefore, all the offspring resulting from this cross will be tall.
