Quantitative inheritance involves the interaction of a number of gene loci.The pattern of genetic transmission typical of quantitative inheritance is ________.
A) discontinuous distributions such as 3:1
B) typical of Mendelian inheritance
C) continuous variation of phenotypic expression
D) a 9:3:3:1 ratio
E) usually a pattern that clearly reflects dominance and recessiveness

Question

Quizplus · Accepted Answer

Quantitative inheritance involves the interaction of multiple gene loci where each locus contributes a small additive effect towards the phenotype, resulting in a continuous distribution of phenotypic expression. This is in contrast to Mendelian inheritance, which involves distinct and predictable ratios of offspring with specific traits based on the dominant and recessive inheritance of single gene loci.
