Snapdragons occur in nature as either green or yellow plants. A green snapdragon is homozygous and has the genotype CC. A yellow
snapdragon is heterozygous and has the genotype Cc. Suppose that a gardener crosses two yellow snapdragons, and one-third of the offspring are green and two-thirds of the offspring are yellow. What type of allele could be responsible for the 2:1 offspring ratio seen when two yellow snapdragons are crossed?
A. dominant allele
B. polymorphic allele
C. recessive lethal allele
D. codominant allele

What type of allele could be responsible for the 2:1 offspring ratio seen when two yellow snapdragons are crossed?
dominant allele
Explanation:
As a result of two yellow snapdragons crossed, the dominat yellow allele gives the reason why the reult reflects in such a way that there is yellow dominates over green and leads to why yellow has two-third while green has one-third
