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

goldfiish [28.3K]

The question is incomplete. The information asked in the question is as follows:

What is your presumptive diagnosis for this case?

Caused by which organism?

What evidence could the sputum give for this case?

Is the increased respiration rate and unequal chest movement indicative of the pathology?

Is this a bacterial or viral disease?

Answer:

Alzheimer disease may be defined as a type of the progressive disorder that mainly destroys the memorizing capacity of the individual. The disease gets worsen with the age.

After studying the case disease given in the question it can be inferred that the individual might have pneumonia caused by the bacteria  Klebsiella. This causes the damage to the lungs. The sputum shows that the bacteria is gram negative that are covered with the rods. If the bacteria is grown on the agar plate of the MacConkey, the bacteria becomes mucoid due to the production of the slime. This might cause the lung damage and causes inflammation that causes the observable changes. This is a bacterial disease.

Sporozoa do not have flagella or cillia for locomotion. So, they are non motile .
