Animals in the same family
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%.
This is referred to as: spontaneous recovery
Spontaneous recovery is a theory of learning and memory which involves unexpected and recurrence of a conditioned response after a period of reduced response or delay. Spontaneous recovery is associated with classical conditioning and operant conditioning. Extinction will happen quickly after a spontaneous recovery, if the conditioned and unconditioned stimulus is not connected.
Answer: On Earth, most carbon is stored in rocks and sediments, while the rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs, or sinks, through which carbon cycles.
