Homework Help: Science

Posted by Axel on Friday, September 24, 2010 at 1:10am.

My original question: In a diploid organism with 2n=8, what is the probability that one of its gametes will contain only paternally derived chromosomes (ie, not a mixture of paternal and maternally derived chromosomes)?

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?
