Hemophilia a is an x-linked recessive disorder. if a normal man marries a woman who is a carrier, what fraction of their daughte
RSB [31]
Daughters get one X gene from each parent.
If the father is a normal male, he carries only a normal X-gene.
Therefore the daughter will always get a normal gene from the father, and a 50% probability getting an affected gene from the mother, therefore 50% chance of becoming a carrier.  The other 50% she will inherit a normal X-gene from each parent, thus a healthy female.

In conclusion, no daughter will have haemophilia from a carrier mother and a normal male.
(however, sons will have a 50% chance of inheriting affected X-gene and hence will have haemophilia).

In this experiment, how many chromosomes were present when meiosis i started? 2. in this experiment, how many nuclei are present
wariber [46]
1. The answer depends on your picture.
DNA is packed and condensed with proteins in the form of chromosomes.

Since the process of division is going to start that means each chromosome will have an X shape. They had the DNA content copied once (in the S phase). The original, plus the copy created, form the X.

You just have to count the number of X's in the picture.

2. The answer is 4 nuclei.
Since the process of division happening is meiosis, that means that four new cells will be originated from a cell that's dividing.
So, four new cells each one with a nucleus, that means 4 nuclei in total.

If this was mitosis, only 2 new cells would be formed which means 2 nuclei

3. The number of chromosomes depends on your picture/exercise.

The answer would be half of the number of chromosomes that you started in the meiosis 1.
This time, chromosomes won't have an X shape since the copies were separated. At the end of the process, each chromosome has just one chromatid.
