Answer:
Different faces between humans
Explanation:
There are various faces between humans is because of meiosis. Meiosis happens at ovary and testes in woman and man body. Normally, at ovary and testes, both produced 23 chromosomes including sex-chromosome (22-autosomal chromosome and 1 sex-chromosome) for each one ovum or sperm. And each ovum and sperm have its own DNA that they carried from dad and mom. So, when 2 different DNA merge with each other, producing brand new DNA. Because of that, the baby that will produced will have different face from his/her mom and dad but similar. This shows varieties in humans faces.
