Answer:
The correct answer would be - Dd Pp.
Explanation:
As it is given that tall D is dominant over dwarf d and smooth plant Pis dominant over pubescent p so the the genotype of dominant trait that is tall and smooth tomato plants would be DDPP
. similarly the recessive trait that is dwarf and pubescent plant would be ddpp
Thus, the cross between these would be -
DD PP x ddpp
And gametes would be - DP,DP, dp, and dp.
So, all the 16 offspring would have Phenotype would be heterozygous tall and smooth and DdPp genotype
.
Thus, the correct answer would be - Dd Pp.
