What is it called when the presenence of 2 different alleles results in an intermediate phenotype?
The answer is A) incomplete dominance.





For example, suppose that you cross a red flower with a white flower (of the same plant type). Red is considered dominant, and the genotype would be "RR". White is considered recessive, and the genotype would be "rr". All offspring would have the genotype of "Rr" and would be pink (an intermediate phenotype).
Reply:We took it at school as "co-dominance" , maybe it's the same as incomplete dominance
Reply:A) incomplete dominance! I'm 100% positive!
