Vedclass · Answer

(A) The total number of plants produced is $140 + 40 = 180$. Since both tall and dwarf plants are produced from the same parent,the parent must be heterozygous $(Tt)$. When a heterozygous plant $(Tt)$ is self-pollinated,the offspring genotypes follow the Mendelian ratio of $1:2:1$ for $TT:Tt:tt$. $TT$ represents homozygous tall plants,$Tt$ represents heterozygous tall plants,and $tt$ represents homozygous dwarf plants. Therefore,the offspring will consist of all three genotypes: $TT, Tt$,and $tt$.

From a single ear of corn,a farmer planted $200$ kernels which produced $140$ tall and $40$ dwarf plants. The genotypes of these offspring are most likely:
