A) two allelic pairs in a dihybrid cross-affect the same phenotypic characteristic.
B) there is incomplete dominance between two alleles of the same gene.
C) there is a large norm of reaction for the genotype.

Question

Quizplus · Accepted Answer

Novel phenotypes can arise when two allelic pairs in a dihybrid cross affect the same phenotypic characteristic (A) and when there is incomplete dominance between two alleles of the same gene (B). Both scenarios can lead to new phenotypic expressions not seen in the parent generation.
