A: Why are children born from the same mum and dad not identical?

in #stemq • 6 years ago

The short answer is that each sperm and egg only contains half of the genetic material of the parent. The distribution of genetic material to sperm/egg is mostly random so each sperm and egg have a unique genetic makeup. So you have a completely unique sperm and a completely unique egg combining to make one unique human :)
