PsyDAG replied: Since 4 of the 8 are paternal,

4/8 * 3/7 * 2/6 * 1/5 = ?

My question: can you explain how he/she got these numbers?

**PsyDAG**, Friday, September 24, 2010 at 3:28amI assume that, if 2n = 8, there are 4 paternal and 4 maternal chromosomes.

The first paternal chromosome will be 4/8, and without replacement, the second will be 3/7, the third, 2/6 and the fourth, 1/5.

The second is 3/7, because only 3 paternal chromosomes are left of the remaining 7.

The progression continues.

I hope this helps you understand the process.
