Hemophilia is a X-linked recessive trait. I will denote it as XA for dominant and Xa for recessive.
Hemophilic male: Xa Y
Carrier female: XA Xa
Cross:
Xa Y
XA XaXA XAY
Xa XaXa XaY
Thus, as shown, of the ratio of two possible female offspring genotypes for Hemophilia, only 1/2 will have the disease; the chance is therefore 50%.
The ratio for male offspring genotypes for Hemophilia is 1/2 as well; the chance is therefore 50%.
Answer:
Plants go through a process called photosynthesis that allows them to take carbon dioxide out of the air and turn it into oxygen and energy. The oxygen will later be breathed in by an animal and go through cellular respiration where it will become CO2 again.
I think the correct answer from the choices listed above is option A.
The first type of cell to differentiate is a neuron. The neurons are
cells that process and transmits information through electrical and
chemical signals. Hope this answers the question.
