Why do offspring sometimes look different from their parents?

So children look like combinations of their parents because they are. Each parent gives half of their genetic material to their children. The combination makes a unique combination of their parents genes. The scientific study of how traits are passed from parents to children is called ‘genetics’.

Why does my son look like his mother?

Y-chromosomes have fewer genes than X-chromosomes and some of them are responsible for the development of male genitals. This is why a boy is more likely to look like his mother. When it comes to girls, they receive X-chromosomes from both parents, so it’s impossible to predict what they will look like.

Intelligence in the normal range is a polygenic trait, meaning that it is influenced by more than one gene, and in the case of intelligence at least 500 genes.
