6 Nov 2009, 11:13 PM  | hsc multiple choice question HELP! You can hide this advertisement by registering. A micrograph of a dividing cell from a mouse showed 19 chromosomes, each consisting of two sister chromatids. the haploid gametes produced by this mouse would contain which one of the following chromosome numbers? a) 76 b) 38 c) 19 d) 10 chromosomes in the male gametes and 9 chromosomes in the female gametes The answer is c) 19. but i don't get why... isnt it that the 19 chromosomes, each with two sister chromatids, is the diploid number? thanks in advance = ) |

6 Nov 2009, 11:13 PM | Re: hsc multiple choice question HELP! i thought the diploid number of chromosomes replicate during the early stages to form two sister chromatids? or it only occurs in meiosis not mitosis?... i saw this question when i was studying for my half yearly and i forgot what year is it from... i only copied down the question and answer. |
