A) a gene pair where one gene comes from each parent.

C) more than one pair of genes where one gene of each pair comes from each parent.

Question

Quizplus · Accepted Answer

Polygenic traits involve multiple pairs of genes, each of which contributes to the phenotype of the trait. These genes can come from both parents, so choice C is the only option that fits this description. Choices A and B describe simple Mendelian inheritance, where traits are determined by a single pair of genes. Choice D is not possible, as polygenic traits require multiple genes.
