Answer:
B.Meiotic abnormalities
Explanation:
Now,the answer is unclear because meiosis is a type of cell division.Going back,meiosis is a process of cell division for sex cells or gametes.Meiosis holds all the genetic information that will be passed to the offspring.Now,meiosis can still undergo errors and what's worse,it can produce mutations.Genetic abnormalities like aneuploidy,a phenomenon where there is a net gain or loss of chromosome,roots to the pairing of homologous chromosomes at the prophase 1 of meiosis.There can be incorrect pairing of chromosomes,and it can result to one chromosome that has no pair.Or,in process of DNA replication,there can be an error in sequencing or an incorrect reading that causes more problems.DNA is a key molecule and genes too,and even if one region in a chromosome or the whole chromosome got lost,some proteins cannot be produced because the instructions for it got lost during the process and therefore cause abnormalities in the whole structure of an organism.
