Is it possible for a child to look exactly like one parent?

Looking more like one parent or the other is dependent on the gene versions each parent has. And which ones happen to get passed down. We have two copies of each of our chromosomes and so have two copies of each of our genes.

Do genes determine all your characteristics?

Like chromosomes, genes also come in pairs. Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color.

Why is it unlikely that any two non identical siblings will look the same?

The color of your hair, the color of your eyes, and the dimples on your cheeks are all controlled in part by your genes. But brothers and sisters don’t look exactly alike because everyone (including parents) actually has two copies of most of their genes. And these copies can be different.

Do all children inherit the same genes from their fathers?

First off, each child will pretty much get the same number of genes from dad. Boys and girls will get a slightly different set but these genes won’t affect the sort of traits you are talking about. And all the sons will get the same number of dad’s genes and the same goes for all the daughters.

Will all of my kids look like 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. Before seeing how these are all possible, we need to take a step back and do a quick review of genes and how they work.

Why do siblings from the same parents sometimes look so different?

This is the reason that siblings from the same parents can sometimes look so dissimilar, because the set of genes in one person can be immensely different from the other, despite having the same parents. It’s not just the genes that shape your physical personality, environmental factors also play a significant role.

Can you predict which parent a child will look like?

That is the beauty of genetics! Because of this it is very difficult to predict beforehand which parent a child will look like. You have a better shot at making some predictions if you know each parent’s DNA but even then you can just make predictions.
