Gametes are haploid cells, the haploid number is n = 23, and each parent could provide half of the centromeres. Hence, the fraction of a man’s gametes that contain centromeres inherited from the same parent is 1/2²³.
--------------------------------------
We know that the diploid number in humans is 2n=46. This means that the haploid number is n=23.
We need to know the fraction of a man’s gametes that contains centromers inherited from the the father or the mother.
A gamete has 23 chromosomes.
<em>Half of the centromers could be inherited by the </em><em>father (1/2)</em><em> and half by the </em><em>mother (1/2)</em><em>. </em>
<em />
So the fraction should be 1/2ⁿ = 1/2 ²³
- 1/2 because half of the centromers could be inherited by the father or the mother
- n because is the haploid number of chromsomes in the gamete ⇒ n = 23
