Lecture 3: Quantitative Genetics 2 Flashcards
1
Q
How is phenotypic correlation calculated?
A
The gradient of a graph showing the measures of two traits from numerous individuals in the same population.
2
Q
Define ‘pleiotropy’.
A
The property of a gene when it affects two or more traits.
3
Q
Define ‘linkage disequilibrium’.
A
Non-random associations among alleles at different loci.
4
Q
Define ‘local adaption’.
A
The best genotype in one environment may not be the best genotype in another.
5
Q
What are selections constraints to evolution?
A
Fecundity and lifespan/ageing, artificial selection for late life fecundity, early life fecundity declined, negative genetic correlation, basis for life history trade offs.
