Monohybrid cross 1:2:1 ratio

The phenomenon in which two true-breeding parents crossed to produce an intermediate offspring (also known as heterozygous) is called incomplete dominance. ... In incomplete dominance, the variants (alleles) are not expressed as dominant or recessive; rather, the dominant allele is expressed in a reduced ratio. Problem: 1:2:1 phenotypic ratio in the F2 generation of a monohybrid cross is a sign of: A) multiple alleles B) incomplete dominance C) polygenic inheritance D) pleiotropy E) complete dominance #Genetics #monohybridCross #incompleteDominance
