The answer to this question is DNA. DNA stands for Deoxyribonucleic acid. When you are forming in your mother's body, the DNA from your parents comes together to make a person...or you. When genes are aligned in certain ways, they copy the traits of another human. This is why you may have feet that look like your dad's, and hands that look like your mom's. It is because some of there genes aligned like yours.
Hope this helps! :)
DNA is passed down from each parent. When they reproduce the male sperm has DNA from the father and the mother has its own.
Parents pass their traits to their offspring through a system of DNA and genetics where half of the child's DNA comes from each parent. Each person's traits are determined by the combination of alleles they inherit, resulting in unique characteristics. Differences among siblings arise from the random nature of gene combination during reproduction.
