UNIT 2
what are the components of phenotypic variance
DEPIGA VARIANCE
it is the percentage of the phenotypic variation that is due to genotypic variations.
HERITABILITY
what are the 2 types of heritability?
BROAD SENSE AND NARROW SENSE HERITABILITY
it is a proportion of the phenotypic variance due to al the genetic factors
BROAD SENSE HERITABILITY
how do you interpret the broad sense heritability
H0- DUE TO ENVIRONMENTAL FACTORS
H100- DUE TO GENOTYPE ONLY
H>0- PARTLY DUE TO GENOTYPE
how do you interpret the narrow sense heritability
h0- DUE TO ENVIRONMENTAL FACTORS
h100- DUE TOMADDITICE GENETIC VARIANCE
h>0- PARTLY DUE TO GENOTYPE
it is a proportion of the phenotypic variance based on the additive genetic variance and also measures how likely an offspring will resemble its parents
NARROW SENSE HERITABILITY
dictate the formulas in components of phenotypic variance
