In the early part of the twentieth century,Nilsson- Ehle and others described experiments showing that multiple loci may be involved in the inheritance of certain traits.Such patterns are often called _____ .
A)continuous traits
B)polygenic traits
C)indeterminate traits
D)threshold traits

Question

Quizplus · Accepted Answer

The term "polygenic traits" refers to traits that are influenced by multiple genes, with each gene having a small effect on the trait. This is what Nilsson-Ehle and others observed in their experiments in the early twentieth century. Choices A, C, and D do not accurately describe this pattern of inheritance. "Continuous traits" refers to traits that vary along a continuum (e.g., height), but not necessarily due to multiple genes. "Indeterminate traits" and "threshold traits" are not common terms used to describe patterns of inheritance.
