In biology and genealogy, the most recent common ancestor (MRCA, also last common ancestor LCA, or concestor) of any set of organisms is the most recent individual from which all organisms in a group are directly descended.</span>
Answer:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Other Info That Might Help:
In contrast, in eukaryotes, all of the cell's chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones. Humans inherit one set of chromosomes from their mother and a second set from their father.

Atrophy
Explanation: Atrophy is the progressive degeneration of muscle or nerve tissue. When you wear a cast for multiple weeks and you’re not allowed to bare weight, your muscles tend to become weaker because you haven’t used it in a while. That’s why PT is recommended after a bone break.
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).
