In humans, the condition for normal blood clotting (H) dominates the condition for non clotting (hemophilia) (h). Both alleles a
Fudgin [204]

Answer:

The correct answer would be - 50%.

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

Alex17521 [72]

Answer:

Binary fission is different from mitosis and meiosis because it occur in prokaryotic cells. And prokaryotic cells does not have nucleus like the eukaryotic cells and there is not mitotic spindle formation during binary fission compared to mitosis and meiosis.

Explanation:

Binary fission is a process of cell division where a single cells divide into two or more parts and the parts regenerate into another organisms which resembles the parent organisms. This occur only in prokaryotic cells and is very different from mitosis and meiosis that occur in eukaryotic cells because prokaryotic cells lack nucleus and no spindle formation in the nucleus.

Mitosis occur in eukaryotic cells because they have nucleus and membrane bound organelles and is the process where a parent cell divide to produce two daughter cells that are genetically identical to the parent cell and each cell having the same number of chromosomes of the parent cell.

Meiosis is a type of cell division that occur in eukaryotic cells and it occur in sex cells where a single cell divide into four daughter cells with each having half number of parent cell chromosomes.
