    Hi, I presume this is a relatively straight forward calculation but it is really confusing me at the minute! Could anybody help me?

    Question: Calculate the number of possible combinations of chromosomes if the diploid number is four? Assume there is no crossing over of chromosomes.

    You have two pairs of chromosomes so let's say they are 1a, 1b, 2a, and 2b. There will be 2 intermediate haploid cells each getting one copy of chromosome 1 and one copy of chromosome 2. So it could be 1a+2a and 1b+2b, or alternatively 1a+2b and 1a+2a. So two possible combinations.
