Define heritability
|
Amount of phenotypic variation among people because of variation in the genotype.
|
|
|
Do important traits usually have high or low heritability?
|
Low-- because there has been strong selective pressure for those traits to be functional
|
|
|
As variation decreases because of selection, does environmental influence increase or decrease?
|
Increase!
|
|
|
When heritability is closer to 0 than 1, what does that mean?
|
Less variation is attributable to the genotype
|
|
|
Can heritability answer the % of variation among people due to genes instead of the environment?
|
Yes, but it can't tell that % for individuals
|
|
|
Why is heritability higher in kids and babies?
|
Because they haven't finished developing and haven't had a lot of environmental influence yet.
