Answer:
are influenced by many different genes
Explanation:
A quantitative trait is a given phenotypic trait influenced by the combined effects of many genes and its environment. A quantitative trait locus (QTL) is a region of DNA (i.e., a <em>locus</em>) associated with the variation of a quantitative trait. In the last years, some QTLs correlated to the variation of HDL, LDL, and triglycerides levels were mapped in different genomic regions, thereby showing that these complex traits are regulated by the interaction of multiple genetic <em>loci</em>.
Answer:
The difference is:
a) Positive feedback increases a change while negative feedback reduces a change.
b) Positive feedback occurs specific situations while negative feedback occurs in the body.
c) Positive feedback break down the homeostasis while negative feedback maintain the conditions of homeostasis.
d) Positive feedback has less frequent mechanism while negative feedback has more frequent mechanism.
e) Positive feedback enhances change while negative feedback resists change.
f) Positive feedback has a wider range while negative feedback has a narrow range.
