The number of chromosomes is halved, yet they exist as duplicated pairs of chromatids (which, as is correctly highlighted, may differ owing to crossing over). Therefore the actual number of chromosomes is still 46 (2 x 23) i.e. not haploid (23), which isn't achieved until after the final division in meiosis 2.Chris"I never forget a face, but in your case I'll make an exception" - Groucho Marx
quote:Originally posted by alastair84sorry to sorta go off topic, I have got a burning question straight from a past exam paper:TRUE/FALSE:Cells entering metaphase of meiosis I contains 4 times the DNA content of a gamete.I am thinking true, as the cell has 92 chromatids, and the gamete has 23 chromatids. anyone agree?
