2. In humans, albinism(a) is recessive to normal skin pigmentation(A). A man with normal skin pigmentation whose mother was an albino, marries an albino woman. Predict the phenotype ratio of their children.

if the man's genotype was Aa then the phenotype of their children would be: 50% albino and  50% normal skin pigmentation.

if the man's genotype was AA then the phenotype of their children would be: 100% normal skin pigmentation.

Explanation:

I almost completely doubt that the answer is the second one since the mom was albino then he has to have the trait in him some where and so his genotype would be Aa. However, I gave you both answers just in case but trust me if u choose one I suggest the first one (50% 50%) because it is the most accurate considering his mom was albino.

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.

because the light is a great source of energy for the plants to survive. (i hope this )
