DNA Sequences That Contribute to Polygenic Traits are Called

Question

DNA sequences that contribute to polygenic traits are called
A) qualitative trait loci.
B) quantitative trait loci.
C) multifactorial trait loci.
D) single nucleotide polymorphisms.
E) polygenes.

Accepted Answer

DNA sequences that contribute to polygenic traits are called quantitative trait loci (QTLs). QTLs are regions of the genome that contain polymorphisms associated with complex traits, where each gene typically contributes a small effect.
