<h2>Allelic frequency </h2>
Explanation:
The B allele will become more common only if the individuals reach reproductive ages
Since the individuals with allele B have much greater reproductive success therefore once they reach the reproductive age, success to reproduce new individuals will be higher
The offsprings will carry on the allele(B allele) and pass on to the next generation
Even if the parental individuals die because of shorter life span the offsprings produced in each generation will pass on the allele to their subsequent generation
Requirements for folate increase by 50 % during pregnancy, Folate plays a vital role in the production of red blood cells and helps the fetus neural tube to develop into her brain and the spinal cord. Pregnant women are advised to increase folate in their diet as folate is important in that it helps to prevent neural tube and other birth defects. Tube defects are serious birth defects of the spinal cord such as spina bifida and the brain such as anencephaly.
