Color in flowers is codominant. If you cross a Heter0zygous spotted flower with a Hom0zygous Red flower, what is the % genotype and % phenotype of the offspring? (Red: R, White: W)

This is an example of codominance where both allelles manifest when present.

we cross RR with RW

the offspring are RR RR RW RW

genotype:

50%RR 50RW

phenotype:

50%red 50%spotted

complete the square on the right side of the equation;

-5(x + 0)^2 + 15

answer: d. y = -x^2 + 15
