5. The table shows the diploid chromosome number of a certain mammals, their approximate body mass in Kg and their genome size in Gbp.[img]data/attachment/exam/2501/24/2501241156212236.jpg[/img]

参考答案: The data does not indicate that a larger genome size has a larger (diploid) number of chromosomes. For example, the largest genome size is 5.4Gbp in the African elephant, but the largest number of chromosomes is 78 in the European wolf (Accept one mark for any relevant numerical example). Chromosomes can have different lengths/ more DNA/a greater or smaller number of base pairs. The size of chromosomes has more effect on chromosome number than genome size. It is a small sample size/the sample is only mammals so the results have a limited reliability for generalising trends (induction) NOTE: Award 2 marks for any 2 points made.
