In snapdragons, red × white produce pink. What best explains this pattern of inheritance?
C. partial dominance.





The red is BB and the white is bb. They cross to produce 4 Bb's which could either be red or pink in the case of incomplete/partial dominance. They are pink therefore it is partial dominance.
Reply:I have known this as incomplete dominance, but I would say that C. partial dominance is the same thing..





So the answer is C. partial domiance.





Neither trait is dominant and neither show up, rather a "blend" or the two show up
Reply:This is an example of equal dominance or co-dominance. From your list, I think hybridization is the best word.


Hope that helps!
