Explanation: 

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: -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-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: -A child receives 50% of genes from father and the rest 50% from mother. Was this answer helpful?
