Question

I was wondering what mechanism causes children born to the same parents all have different characteristics from each other. I understand that half the Chromosomes come from the father and half the Mother so you'll always get a mixture of both parents characteristics. However, this simple understanding doesn't explain why they aren't all identical twins (albeit born at different times). So are the Chromosomes somehow jumbled further say chromosomes no. 2 from Mum and no. 4 from Dad? What mechanism controls individuality?

Explanation / Answer

So to understand real individuality really have to understand how you and I were made. It really starts when a sperm from your dad and an egg from your mum got together and made you as an individual. Sperm and egg are made by a special form of cell division, which is called meiosis.

Meiosis is special because it turns a diploid, which has two copies of every chromosome, into a haploid, which has one copy of every chromosome. So, when cells goes through the process of meiosis, you take this 46 human chromosomes and you turn it to a cell with one copy of every chromosome, which now means has only 23 chromosomes.

And very importantly, this process of meiosis is random. Every cell that goes through meiosis will inherit one of every chromosome, but whether inherits one from your mother or father is random. So for example, when your father
