16
Q

Gene-gene interaction Consequences/Comment

A

This pattern leads to one allele being associated with different phenotypes

17
Q

Gene-environment interaction Definition

A

Phenotype is influenced by the environment experienced by the same individuals with the same genotype

18
Q

Gene-environment interactions Consequences/Comment

A

Same genotypes can lead to different phenotypes

19
Q

Polygenic Inheritance of Quantitative Traits Definition

A

A trait that exhibits continuous variation rather than coming in distinct types

20
Q

Polygenic Inheritance of Quantitative Traits Consequences/Commentg

A

Unlike alleles that determine discrete traits, each allele adds a small amount to phenotype
