i think it was harder than last year's paper...

question 7 was a bit of a bugger

the only thing in the bio papers is that you dont know whether your right or your rong, as it depends on the markschemes :/

because it contains full set of chromosomes they are diploid while gametes are haploid .

no the only characteristic for gametes r that they r haploid whereas somatic cells have diploid cells therefore its more accurate and reliable results as u could see all mutations if there r on each chromosome not only half!!!!!
