Answer:
C. antigen-antibody reactions
Explanation:
human blood group is determined by the presence of antigens on the red blood cells which are specific proteins.
so specific antibodies are used against these antigens to determine the type of blood group after the reaction.
These three factors affect how variations in genotype arise in a population:
<span>1) Sexual recombination- one-half of the parent 1 and one-half of parent 2’s genes are combined to form a brand new gene for the offspring resulting to a new type of combination that is not existing before.
2) Gene crossover- this is the trade-in of genetic material from two cells that each contains a pair or 1 maternal strand and 1 paternal strand of the parents chromosomes (Homologous).
</span>3) Chromosome aberration- it is a mutation in the chromosome wherein there is an extra or missing part of the DNA. <span> </span>
