NEET BIOLOGY

Detailed explanation-1: -Your DNA contains a record of your ancestors, but you aren’t a carbon copy of any one of them. The particular mix of DNA you inherit is unique to you. You receive 50% of your DNA from each of your parents, who received 50% of theirs from each of their parents, and so on.

Detailed explanation-2: -After all, children inherit half of their DNA from each parent: 50 percent from mom (through an egg), and 50 percent from dad (through sperm). So how can biological siblings have different results?

Detailed explanation-3: -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-4: -Only Parents and Children Always Share an Exact Amount of DNA. So there you have it. Most everyone shares 50% of their DNA with their mom and 50% with their dad. In other words, sons and daughters are pretty much always 50% related to mom and 50% to dad.
