The meiotic central spindle is comprised of two interconnected arrays of microtubules. a Partial spindle reconstructions for mid- (left) and late (right) anaphase I chromosomal microtubule arrays. Model of chromosomes (magenta) and either polar body (PB) proximal microtubules (orange), future maternal pronucleus (PN) proximal microtubules (yellow), or microtubules which contact both chromosome masses (red). b Length distribution of fully contained microtubules in the chromosomal microtubule arrays for mid- (orange) and late (blue) anaphase I spindle reconstructions. c Partial spindle reconstructions for mid- (left) and late (right) anaphase I central microtubule arrays. Model of chromosomes (magenta) and microtubules (green). d Length distribution of fully contained microtubules in the central array for mid- (orange) and late (blue) anaphase I spindle reconstructions. e Microtubule length distribution within partial spindle reconstructions for mid-anaphase I central (far left) and chromosomal (left) microtubule arrays, and late anaphase I central (right) and chromosomal (far right) microtubule arrays. Microtubules are color-coded according to their length as indicated. Scale bars, 1 µm. f Quantification of microtubule overlaps >200 nm in length for the indicated populations
