The extra X chromosome is received from mother.
<h3><u>Explanation</u>:</h3>
Klinefelter's syndrome is the condition of chromosomal aberration where the person has an extra X chromosome. This means the genotype of the person is 44+XXY and the total chromosome number is 47. This condition is achieved due to inappropriate meiotic division and one of the sperm or ovum has the an extra X chromosome.
Here both the parents are normal in terms of colour vision. So the father cannot have the gene of colour blindness because if it was present, then father would have been colour blind because he has only one X chromosome per cell. So its present in mother who is heterozygous in terms of colour blind gene. So the extra X chromosome also came from her which made the presence of two defective X chromosomes in the offspring and made it colour blind.

I wish i knew the answer to this.
For humans, the diploid chromosome number equation is 2n = 46 because humans have two sets of 23 chromosomes The diploid chromosome number varies by organism and ranges from 10 to 50 chromosomes per cell.
<h3>What is Mitosis?</h3>
Mitosis is a type of cell division that occurs in somatic or body cells. In mitosis, and a cell undergoes division to produce two daughter cells each with the same number of chromosome as the parent cells.
Mitosis produces diploid cells and diploid cells are cells that have the same number of chromosomes as the parent cell.
Thus, The diploid chromosome number varies by organism and ranges from 10 to 50 chromosomes per cell.

Plasma membrane is a part of the cell made of a lipid bilayer and an embedded protein layer. It protects the cell from the surroundings and also controls the materials leaving or entering the cell. The membrane is semipermeable and therefore allows certain materials to enter or leave the cell. In this case, the plasma membrane may prevent unlimited flow of water into or out of the cell.
