Question

Red and white roses are cross-bred (neither are dominant). The offspring would be ,because of

Answer 1

The offspring would be different depending on what type of breeding you did, because of the fact there are different breeding techniques. Co- dominant means it would be patchy with a combination of both, like when breeding cows. The other technique is incomplete dominance, which is where both the colors ( in this case red and white) mix together to make a different color. But to simplify it, it would most likely be half and half because both genes are recessive. 

Answer 2

Answer: The correct answer is- The offspring would be pink because of incomplete dominance.

Explanation-

Incomplete dominance produces a blend/ intermediate phenotype of both the parental phenotypes ( such as Pink in produced in this case) because none of the parental allele completely masks the effect of other.

As per the information given in the question, neither of the rose is dominant. This means that when both are cross bred, they will represent a heterozygous state ( when alleles for both the rose are present ), and they will produce an intermediate phenotype ( that is a blend of both the traits, which is pink).
