Detailed explanation-1: -Sometimes children end up looking exactly like one parent, or even closely mirroring a sibling, and sometimes they don’t resemble anyone in the family. It’s all entirely possible. Kids share 50% of their DNA with each of their parents and siblings, so there’s plenty of room for variation.
Detailed explanation-2: -So, yes it is possible for a child to look like someone who they do not share dna.
Detailed explanation-3: -All of the different combinations of these genes come together to determine how you look. Even though we get all our DNA from our parents, each of us has a unique combination of genes. Sometimes that means we don’t look like them at all. There are tons of genes that shape our appearance.
Detailed explanation-4: -Genetics 101. In our examples, I will focus on a red haired, blue eyed mom and a brown haired, brown eyed dad. As you’ll see, in some cases all the kids will look like dad and in others, they’ll come out looking like dad, mom, or a combination of the two.
