(B) This is an example of polygenic inheritance. The number of phenotypic categories in polygenic inheritance is given by the formula $(2n + 1)$,where $n$ is the number of gene loci involved.Given that the number of phenotypic categories is $7$,we can set up the equation: $2n + 1 = 7$.Solving for $n$: $2n = 6$,which gives $n = 3$.Therefore,$3$ gene loci are involved in determining the weight of the fruits.

In a plant,the weight of fruits is determined by the number of dominant alleles for several genes. If seven categories of weight are obtained,how many loci are involved in this trait?
