What percentage that newborns will look like their parents?

Answer 1

Newborns will alway look like their parents because of the way that they are made.

Embryos are a collection of cells that originated from two cells - the sperm cell and the egg cell. They then split and divide to eventually turn into a baby.

The Genetic information passed onto the baby comes half from the mother and half from the father, meaning that the baby will always have characteristics of both the mother and fathers because of dominant and recessive genes being passed onto the child, such as connected earlobes or brown eyes.

However characteristics that for example the grandmother had that the baby receives is because of dominant or recessive genes that were passed on in the (for example) mothers genetic makeup, that when she was made, was overpowered by a gene passed onto her from the grandfather.
