Question

Quizplus · Accepted Answer

Quantitative inheritance is characterized by continuous variation in phenotypic expression. This means that there is no clear-cut distinction between different phenotypes and instead, the traits are expressed as a range of values. Unlike Mendelian inheritance, the patterns of genetic transmission in quantitative inheritance involve the interaction of many gene loci, with each contributing a small effect towards the phenotype. There is no clear pattern of dominance and recessiveness, and the inheritance cannot be described by simple ratios such as 3:1 or 9:3:3:1.
