Term
Dominant and recessive alleles are relative to...
Definition
the strength of the allele
Term
Whenever there’s 2 alleles in the same location, this will happen
Definition
interaction between those alleles
Term
Dominance
Definition
interaction between alternate alleles within a locus
Term
types of dominance
Definition
-complete dominance
-incomplete dominance
-codominance
-overdominance
-underdominance
Term
Complete dominance
Definition
the expression of the allele completely masks the recessive allele
Term
Incomplete dominance
Definition
yields an intermediate between the 2 parental phenotypes
Term
example of incomplete dominance
Definition
red + white ---> pink
Term
example of incomplete dominance in chickens
Definition
frizzle feathers (this is between normal and extreme)
Term
Codominance
Definition
both of the phenotypes of the parents are displayed in the heterozygote
Term
example of codominance
Definition
black + white ---> speckled black and white
Term
Overdominance
Definition
phenotype of one of the parents is expressed in a more pronounced way
Term
example of overdominance
Definition
red + white ---> deep red
Term
Underdominance
Definition
hybridization reduces expression of one of the phenotypes
Term
example of underdominance
Definition
deep blue + blue yields light blue
Term
phenotypic ratio in a dihybrid cross with complete dominance
Definition
3:1
Term
phenotypic ratio in a dihybrid cross with incomplete dominance
Definition
1:2:1
