Answer:
A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).
Explanation:
Cyanide prevents the production of oxygen
Erosion affects the environment in a number of ways, such as the falling of trees, the flooding of forests, destruction from wind erosion, and a number of others. The one I'm focusing on in this section though issoil erosion. There are two different types of soil erosion; Wind and Water.
As a glacier moves, particularly a warm glacier, it causes erosion of the underlying surface. However, ice doesn't seem as if it should be a particularly effective material for wearing away hard rocks, so how do glaciers manage to produce such large erosional features?<span>Material from underlying bedrock or sediment is picked up by the glacier and 'held' in the ice as it moves. Material falling onto the surface (often the result of freeze-thaw activity, or frost shattering, on the surrounding rock walls) is also transported, and often finds its way down through crevasses to the base of the glacier. Material held within the glacier is called 'englacial moraine'. It is this material trapped in the ice, that allows the glacier to erode its surroundings.</span>
A woman with type O blood is expecting a child. Her husband is type A. Both the woman's father and her husband's father had type B blood. What is the probability that the child will have type O blood?
a)25% B) 50% C) 75% D) 100%
Answer:
B) 50%
Explanation:
The father of the husband has blood type B. This means that the husband cannot be homozygous for IA allele and has genotype IAi. The genotype of the woman with respect to blood type O will be "ii".
A cross between IAi and ii would produce progeny in following phenotype ratio= 1/2 blood type A: 1/2 blood type O
Therefore, there are 50% chances for this couple to have a child with blood type O.
