Heritability Flashcards
measure of resemblance between relative
heritability
describes the proportion of total phenotypic variation in a population due to genetic factors
heritability
gives the proportion of phenotypic variation attributed to genetic variation within a certain population in a particular environment
heritability estimate
can be estimated using variance components
heritability
What are the two types of heritability
Heritability in the broad sense
Heritability in the narrow sense
most predictable among the sources of genotypic variance
additive gene effects
the relationship between the additive variance and the total phenotypic variance is generally used as a measure of
heritability
concerned with how much of the parents’ phenotype is passed on to the progeny
heritability in the narrow sense
concerned with how much of an individual’s phenotype is caused by the genotype
heritability in the broad sense
what is the most direct way of estimating broad sense heritability?
measuring the variance of a group of genetically identical individuals
the variance of genetically identical individual is entirely due to
environment
What are the sources of variation of P1 and P2?
Environment
What is the source of variation of F1?
Environment
What is the source of variation of F2?
