Remember that in humans 2n = 46. What fraction of a man’s gametes contains centromers all of which were inherited from the same parent of that person? (it can be the dad or the mom of that guy, does not matter)

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.

Half of the centromers could be inherited by the father (1/2) and half by the mother (1/2).

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
