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).
Detailed explanation-3: -The autosomes (chromosomes 1–22) are passed down equally from each parent; one copy from each parent. Therefore, a parent and a son or daughter would share 50% of their autosomal DNA.
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.
