A woman with normal blood clotting ability whose father was a hemophiliac and whose mother was normal with no family history of
Alborosie

Answer:

The answer is 25%.

Explanation:

Hemophilia is a recessive illness that is x-linked.

If the husband has normal clotting ability, that means he has the dominant gene since he has only one X chromosome.

Since there is a probability that their child will have hemophilia, this means that the woman, who has 2 X chromosomes but has normal blood clotting abilities, has one dominant and one recessive hemophilia gene.

The probability that their first child will be a male is 50% and the probability that he will have hemophilia is also 50% since he will only get the Y chromosome from the father and the mother has one dominant and one recessive.

So the probability that their first child will be a son with hemophilia is 25%.

I hope this answer helps.

How does the human heart level of organization relate to cells? To organ systems
ANEK [815]
It is hard to understand this question but ill give you my best answer. The hearts level of organisation to cells is immense, the heart pumps blood to every cell in the body (so they can respire) through a system of Arteries, veins and capillaries. The blood is pushed by the force of the heart through the arteries, the main (and largest) tubes for transportation to segments of the body further away from the heart. This goes into a smaller system of veins that brake off into a tree kind of pattern to reach every cell. These later brake off into the capillaries that have walls only 1 cell thick. This is how blood is transported to each cell that requires energy and oxygen to respire.

abruzzese [7]
The answer is unsupported claims.

Pseudoscience is not actual science. While science is based in logical reasoning, pseudoscience consists of statements, beliefs, or practices that don't have evidence to support them but they claim to be scientific and factual (some examples: homeopathy, geocentrism, reiki, flat earth theory)
