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

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?
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
Multicellular organisms can be much larger and more complex. This is because the cells of the organism have specialised into many different types of cells such as nerve cells, blood cells, muscle cells all performing different functions.
Cells function better at smaller units because if each cell had more areas in the body to take care of, they would need to do more hard work then they already do. Also, if we got scraped, we would lose less small cells then bigger cells. I hope this helped you!
The correct option is D) The birds have different mating seasons.
Explanation:
Organisms belonging to the same species will have the ability to reproduce and produce fertile offsprings. As the birds have different mating seasons, this means that the birds are not able to mate and reproduce at the same time. Thus phenomenon supports the second student's argument.
