Genetic Exception

Multiple genes and the environment play a role in the phenotype

• epistasis

• codominance

• multifactorial

• multiple alleles

Phenotype is similar to an inherited trait but is caused by the environment

• phenocopy

• epistasis

• lethal allele

• penetrance

NGSS.HS-LS2-6

NGSS.HS-LS4-5

Each allele is equally dominant and the phenotype is distinct

• phenocopy

• pleitropy

• epistasis

• codominant

Phenotype will result in death at some point

• epistasis

• lethal allele

• expressivity

• incomplete dominance

One gene masks the effects of another genes phenotype

• complete dominance

• incomplete dominance

• epistasis

• polygenic

More than two alleles for a given trait

• multiple alleles

• codominance

• pleitropy

• phenocopy

Degree to which a trait varies among individuals

• expressivity

• penetrance

• epistasis

• pleitropy
