proportion of a population’s phenotypic variation that is attributable to genetic factors

• Heitability
• Allelism
• Phenotypic Alignment
• Transposition

used to examine the relative contributions of genes and environment to variation in a specific trait

• Heitability
• Allelism
• Phenotypic Alignment
• Transposition

how much of the phenotypic variance can be attributed to genetic variance

• Braod sense heritability (h2B)
• Narrow sense heritability (h2N)
• none of the above

Vg/Vp

• Braod sense heritability (h2B)
• Narrow sense heritability (h2N)
• none of the above

means none of the variation in phenotype among individuals results from genetic differences

• h2B = 0
• H2B = 0.5
• H2B = 1.0
• None of the above

50% of the phenotypic variation arises from genetic differences among individuals

• h2B = 0
• H2B = 0.5
• H2B = 1.0
• None of the above

phenotypic variance is genetically based

• h2B = 0
• H2B = 0.5
• H2B = 1.0
• None of the above

can heritability indicate which proporiton of indivduals phenotype is genetic?

• No, because it is based on variance and group of individuals not genetic sequencing
• No, because it is based on genetic sequencing and not on group of individuals and variance
• Yes, because it is based on variance and group of individuals not genetic sequencing
• Yes, because it is based on genetic sequencing and not on group of individuals and variance

heritibaility is not fixed for a trait because it is dependent on both ___

• genetic make-up
• specific environment
• number of traits under consideration
• ecological niche of neighboring populations

includes genetic variation from all types of genes

• Braod sense heritability (h2B)
• Narrow sense heritability (h2N)
• none of the above
