Detailed explanation-1: -While women do inherit 50% of their DNA from each parent, men inherit about 51% from their mother and only 49% from their father.
Detailed explanation-2: -You receive 50% of your genes from each of your parents, but the percentages of DNA you received from ancestors at the grandparent level and further back are not necessarily neatly divided in two with each generation.
Detailed explanation-3: -Genetically, you actually carry more of your mother’s genes than your father’s. That’s because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.
Detailed explanation-4: -Among the many things parents hand down to their children are 23 pairs of chromosomes – those thread-like structures in the nucleus of every cell containing the genetic instructions for every person. We inherit a set of 23 chromosomes from our mothers and another set of 23 from our fathers.
