    There is one diagram (9700/11/o/n/12 question 19)
    It shows chromosomes in metaphase
    having 5 sets of chromosomes at each pole.

    For example if this is a chromosome X
    made from / and \

    is the total number of / and \ called haploid
    or the total number of X is called haploid ?

    in the markscheme it is written that no. of X is haploid
    but i dont get it
    isnt n supposed to be haploid and 2n is diploid ??
    which means no. of / and \ is haploid ??

    I hope u understood
    plz reply

    Haploid cells (example: sperm and ova) contain only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes. It's unclear what the question is, but hopefully this definition of haploid will help you. Are the / and \ supposed to be chromatin? I don't think they're individual chromosomes, and that the X is just two chromatids creating a single haploid chromosome.
If you won £30,000, which of these would you spend it on?
