Thus, there may be an evolutionarily conserved asymmetry in the metaphase checkpoint, which may reveal something about its mechanism. This 'pronucleus' condenses at first mitotic metaphase to 40 somatic chromosomes which coexist with 20 egg cell chromosomes. A mitotic heterokaryon carries thus a unique metaphase plate composed of 20 somatic chromosomes of egg-cell origin and 20 meiotic bivalents. First, we induced a metaphase arrest in the deep cell layer by treatment with 0.5ug/ml nocodazole. They are then hybridized together onto prepared slides of human metaphase chromosomes, which act as indicators. For each chromosome, a ratio value of fluorochrome intensity is generated from a minimum of five metaphase spreads. On metaphase spreads chromosomes are usually in a single group. C-bands in human metaphase chromosomes treated by barium hydroxide. An extension of this examined the possibility of checkpoints during meiosis itself, specifically during metaphase. In this study, we addressed the developmental activation of the metaphase checkpoint in the zebrafish embryo. This indicates that neither aster is strongly attached to the cortex until the end of metaphase. The chromosomes (red) were aligned on the metaphase plate. A gain of a chromosomal region would be shown by an increased intensity of the green fluorescence in the reference metaphase preparation. We only examined embryos showing more than five metaphase spread cells to define as either diploid or tetraploid embryo. These examples are from corpora and from sources on the web.
