<u>Explanation:</u>
<em>Centromeres is defined as the part of the DNA</em> which are held responsible for the directional changing of chromosomes.
And these chromosome gets divided into <em>2 daughter cells while undergoing the process of mitosis and meiosis. </em>

Blood type is determined by the alleles coding for the antigen present on cell membranes.
The person with type AB blood has a heterozygous Rh factor.
- Half the gametes have Rh factor (+) and the other half are negative for Rh factor (-)
- Half the gametes have IA and the other half have IB
- The possible gamete combinations are IA+, IA-, IB+, IB-
The person with heterozygous type A blood is negative for Rh factor
- All gametes are negative for Rh factor (-)
- Half the gametes have IA and the other half have IO
- The possible gametes are IA-, IO-
The genotype ratio is 1:1:1:1:1:1:1:1
The phenotype ratio is 2: 2:1:1:1:1.
