The comb shape of chickens is an example of an interesting inheritance pattern.
Two genes, each with a dominant and recessive allele, determine combphenotypes as follows:
The inheritance pattern of the comb shapes of chickens is an example of
Two genes, each with a dominant and recessive allele, determine comb
Comb Shape | Description | Genotype |
---|---|---|
Single Comb | homozygous recessive for both r and p | rrpp |
Walnut comb | both dominant alleles are present; R and P alleles are present | R_P_ |
Pea comb | the dominant allele P is present and the dominant allele R is absent | rrP_ |
Rose comb | the dominant allele R is present and the dominant allele P is absent | R_pp |
The inheritance pattern of the comb shapes of chickens is an example of
Select one:
a. complementary interaction
b. suppression epistasis
c. codominance
