A number of interacting genes produce quantitative inheritance.The transmission of these genes can be seen in the phenotypical pattern of
A)discontinuous distribution of discrete phenotypes.
B)continuous variation in phenotypic expression.
C)strict dominance and recessiveness.
D)All of the choices are correct.
E)only discontinuous distribution of discrete phenotypes and continuous variation in phenotypic expression.

Question

Quizplus · Accepted Answer

Quantitative inheritance is characterized by continuous variation in phenotypic expression, which is a result of the interactions of multiple genes. This means that there is no clear-cut distinction between discrete phenotypes, and instead, individuals display a range of intermediate phenotypes. Therefore, choice B is the correct answer. Choices A, C, D, and E are incorrect because they do not fully capture the nature of quantitative inheritance.
