Explanation:
Hemophilia is a sex-linked recessive disorder that takes place in males more than in females as females have two X chromosomes so if one is affected other still able to make clotting factors but in males, there are only one x chromosome.
If a hemophilic man XhY marries with a carrier women XHXh then the chances of their son for normal blooding would be :
Gametes:
Male: Xh and Y
Female: XH and Xh
Then cross:
Xh Y
XH XHXh XHY
(carrier daughter) (normal son)
Xh XhXh XhY
(hemophilic daughter) (hemophilic son)
Thus, the chances of normal son is 50% among sons
During mitosis, the number of individual chromatids that will align during metaphase is 4 and the sister chromatids are not paired up each other.

Answer:
False.
Explanation:
Three domains of life are bacteria, eukarya and archaea. The prokaryotic organisms are involved in the bacteria and archaea. Eukaryotic organisms are included in the domain eukarya.
The archaea are more similar to eukarya than bacteria. The cell walls of the archaea are made of glycerol-ether lipids. The phospholipids of archaea are built on a backbone of sn-glycerol-1-phosphate. Archaea lacks the peptidoglycan layer in its cell wall.
Thus, the answer is false.
