Detailed explanation-1: -To form a fetus, an egg from the mother and sperm from the father come together. The egg and sperm each have one half of a set of chromosomes. The egg and sperm together give the baby the full set of chromosomes. So, half the baby’s DNA comes from the mother and half comes from the father.
Detailed explanation-2: -We inherit a set of 23 chromosomes from our mothers and another set of 23 from our fathers. One of those pairs are the chromosomes that determine the biological sex of a child – girls have an XX pair and boys have an XY pair, with very rare exceptions in certain disorders.
Detailed explanation-3: -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-4: -Most of us have 23 pairs of chromosomes, for 46 in total. You get one of each pair from your mom, and the other one from your dad! That means you get exactly half your DNA from each parent. 22 of these chromosome pairs are the same between men and women.
