Lecture 24 - "real world" genetics II Flashcards
1
Q
what type of traits are the majority of traits in the human genome?
A
polygenetic traits
2
Q
what is another name for continuous traits?
A
quantitative traits
3
Q
what is the equation for phenotypic variation in a population?
A
Vp = Vg + Ve + Vge
Vg - variation due to genotype
Ve - variation due to environment
Vge - variation to the genotypes and their interaction with the environment
4
Q
what is the formula for heritability?
A
H^2 = Vg/Vp
5
Q
what happens when H^2 approaches 1?
A
the genotype completely determines the phenotype
6
Q
what happens when H^2 approaches 0?
A
the genotype has no effect on the phenotype
