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%.

Weathering is the travel from wind that leads to things being in new places like seeds.
Infiltration is adding things in to something, such as adding salt to water.
Answer:Determinants
Explanation:
Determinant covers causes, risk factors, mode of transmission (why and how)
Answer:
Basically, together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
