16.2. Mendelian Definitions Flashcards
1
Q
Multiple alleles of a gene…
A
Produces a range of phenotypes.
2
Q
Incomplete dominance…
A
Neither allele is dominant, therefore a heterozygote displays an intermediate phenotype.
3
Q
Codominance…
A
Alleles produce two independent phenotypes that are both displayed.
4
Q
Pleiotropic allele…
A
One allele has multiple phenotypic effects.
5
Q
Epistasis…
A
One gene alters the phenotypic expression of another.
6
Q
Polygenic traits…
A
Traits controlled by multiple genes (such as height in humans).
7
Q
Incomplete penetrance…
A
Variable phenotypic expression of genotype.
