In crossing the four o'clock flowers, red and white flowers produce pink flowers. this is an example of ...

i take 9th grade biology and the first person is right. its an example of incomplete dominance.





this is from my notes in bio:





Incomplete dominance occurs when both alleles are expressed; the heterozygous phenotype is somewhere in between the 2 homozygous phenotypes.


Ex. Japaneses 4 o'clock flowers


A red flower crossed with a white flower will result in..


Let RR= red and WW= white


100% RW which is 100% pink flowers





Codominance is what the second answerer said.


Codominance occurs when both alleles are expressed and they contribute to the phenotype.


Ex. Chicken feathers


A chicken with black feathers crossed with a chicken with white feathers will result in...


Let BB= black and WW= white


100% BW which is 100% "erminette" feathers (black and white speckled)
