A woman with type AB blood has children with a man who has type o blood. What are the chances they will have a child with type o blood? 25%
0%
100%
50%

The chance of a woman with an AB blood type and a man with an O blood type having a child with O blood is 0%.

Explanation:

A mother with blood type AB (AB) will pass either antigen A or antigen B to the offspring, while the father with blood type O (OO) will not pass any antigen.

The result of an AB X OO cross would be

Alleles        O        O

A                AO     AO

B                BO     BO

For this reason, the offspring of this couple will be

Heredity of blood type depends on the presence of surface antigens on the erythrocyte membrane. Blood type O occurs in persons whose red blood cells do not possess surface antigens A or B.

Surface antigens are what determine blood type, so :

Blood type O has no antigens, and for blood type O to manifest, it must have both alleles for O.

A mother AB and father O cannot have offspring with blood type O.

the answer is tropical areas. the tropical areas obtain more

radiant energy from the sun than they lose to space through terrestrial

radiation, and vice versa for polar areas. earth has an energy remaining in the

tropics and an energy scarcity for the polar areas.
