Problem:

During metaphase, the chromosomes are arranged on the equatorial plate and are attached to spindle fibres. After S phase, can the cell be said to attain the configuration of 4n?
Also, during metaphase, since two spindle fibres (one from say right centriole and other from say left centriole) are attached to one tetrad, so can it be said in a well defined pattern that for a human being, 46*2=92 spindle fibres are formed in order to proceed with mitosis?

Question: How would the number vary in case of Meiosis I and Meiosis II? Please explain.
