Explanation:
Detailed explanation-1: –For the nearly 5, 000 sperm that make it into the utero-tubal junction, around 1, 000 of these reach the inside of the Fallopian tube.-For the 1, 000 sperm entering the tube, only around 200 actually reach the egg.-In the end, only 1 lucky sperm out of this group of 200 actually penetrates and fertilizes the egg!
Detailed explanation-2: -If one egg is fertilised by two sperm, it results in three sets of chromosomes, rather than the standard two-one from the mother and two from the father. And, according to researchers, three sets of chromosomes are “typically incompatible with life and embryos do not usually survive".
