When selection for increased body weight also causes an increase in mature size because the two traits have a positive genetic correlation, this is called:
Correct answer: C. Correlated response to selection
- A. Genetic drift
- B. Inbreeding depression
- C. Correlated response to selection
- D. Phenotypic plasticity
Explanation
A correlated response occurs when selection for one trait changes another genetically correlated trait. In this case, selecting for body weight indirectly changes mature size.

About Animal Breeding and Genetics
Covers genes, chromosomes, inheritance, genetic variation, mutations, heritability and quantitative traits in livestock. It also includes selection methods, breeding systems, inbreeding, crossbreeding, heterosis and evaluation of traits such as growth, milk yield, fertility and disease resistance.

A trait such as milk production is expressed phenotypically only in female animals, although genes influencing it are present in both sexes. This trait is classified as:
In a cattle breed, red coat colour is homozygous RR, white coat colour is WW, and roan is RW. What phenotypic ratio is expected from mating two roan cattle?
Which measure is most directly used to express the genetic merit of an animal for selection purposes?
A gene interaction occurs when the effect of one gene masks or modifies the expression of another gene at a different locus. This interaction is called:
A balanced reciprocal translocation in a breeding animal may reduce fertility mainly because it can produce:
Which evaluation method combines an animal's own records, relatives' records, and information from fixed environmental effects to predict its genetic merit?
