(C) The genotype of the $F_1$ generation plant is $TtRr$. According to the law of independent assortment,the number of types of gametes produced by an organism is calculated using the formula $2^n$,where $n$ is the number of heterozygous gene pairs. In the genotype $TtRr$,there are two heterozygous pairs ($Tt$ and $Rr$),so $n = 2$. Therefore,the number of types of gametes = $2^2 = 4$. The four types of gametes produced are $TR$,$Tr$,$tR$,and $tr$.
