Answer:
In the case of these two parents, a quarter of their children would have blue eyes.
Explanation:
It is not only possible, it is expected that this would happen an appreciable fraction of the time. Brown eyes are dominant. Suppose eye color were dependent on a single Mendelian gene with two alleles, Br for Brown eyes and Bl for Blue eyes. (As Tracey Bryan has explained, this is not true -- I want to explain what the answer would be even in the simple case.) This means the three possible combinations of two alleles give the following eye colors:
BrBr => Brown
BrBl => Brown
BlBl => Blue
Now suppose two brown-eyed people have a child. We can't tell from the fact that they have brown eyes which pairs of alleles they have. Each of them could have either BrBr or BrBl. Suppose they each have BrBl. When they are crossed (i.e., they have a child), the child gets one allele from its mother -- it has a 50-50 chance of getting either one -- and one allele from its father -- again it has a 50-50 chance of getting either one. So, the child has:
25% chance of getting Br from mother and Br from father => brown eyes;
25% chance of getting Br from mother and Bl from father => brown eyes;
25% chance of getting Bl from mother and Br from father => brown eyes;
25% chance of getting Bl from mother and Bl from father => blue eyes.
So in the case of these two parents, a quarter of their children would have blue eyes.
It’s the second one. In photosynthesis plants take carbon dioxide and water to make glucose and oxygen. Hope this helps!
Traits are inherited trough the parents genes that are passed to the offspring trough both parents reproductive cells, that contain genes in their nucleus.
Hope it helped,
Happy homework/ study/ exam!
Photosynthesis is the answer
Force is a vector quantity.
A vector quantity has magnitude and direction which makes it different from the scalar form of quantity. Scalar has only magnitude or size or degree of amount.
For example, acceleration. The velocity, displacement and pressure.
