Occasionally more than one sperm penetrates and enters a human secondary oocyte. The result is formation of a multiple spindles and disruption of the first mitotic division. Explain why the presence of multiple sperm has this lethal disruptive effect.
To explain: The presence of multiple sperms has a lethal disruptive effect on the first mitotic division.
Concept introduction: Spindle fibers are the microtubules that arise from the centriole that align chromosomes in the cell. The spindle fibers, during the fusion of male and female pronucleus, play a major role in diploid chromosome assembly. Polyspermy is the condition where more than one sperm unites with one single ovum.
The male sperm has centrioles present in it. At the time of fertilization, the centriole replicates. The two centrioles constitute the centrosome. The microtubules arise from the centrioles and help to assemble the chromosomes during mitosis...
