Re: AQA BIOL2 ~ 21 May 2012 ~ AS BiologyHere's the question to make it easier for any1:(Original post by samfreak)
I'm stuck on this question - aqa june 2010 question paper, question 5dii, "how many different types of gametes....."
i dont understand why the answer is 5, could someone please explain?
5(d) Figure 5 shows a cell with six chromosomes.
5(d)i) This cell produces gametes by Meiosis. Draw a Diagram to show the chromosomes in one of the gametes. (2 marks)
5(d)ii) How many different types of gametes could be produced from this cell as a result of different combinations of maternal and paternal chromosomes. (1 mark)
Ok, firstly, the answer is 8, not 5.
And secondly here is exactly how to do it I wanted to know aswell >_< I forgot too >

An easier way to do is just
When n = number of homologous pairs
So
But the thread that Sorro linked to will help you to understand where that came from better
But once you understand, its quicker to just do it as
Edit: I just realised that was mentioned at the top of that thread, skimmed passed it. But there you go anyway
