Human cells have 23 pairs of chromosomes.
During transmission of genetic material from one generation to the next, corresponding sections of maternal and paternal chromosome copies are sometimes exchanged (genetic recombination).
The results are discussed in comparison with existing data on chromosomes of aspidogastrean species and other related helminth groups.
Unprotected freezing of human spermatozoa exerts a detrimental effect on their oocyte activating capacity and chromosome integrity.
The experiments should also be begun as soon as the chromosomes are extracted.
This is much larger than the value for chromosomes from nature, as might be expected since it involves an arithmetic rather than a harmonic mean.
The stages at which human fertilization arrests: microtubule and chromosome configurations in inseminated oocytes which failed to complete fertilization and development in humans.
In the simulations reported below, individuals consist of 7 chromosomes, each experiencing an average of 1 recombination event per chromosome.
Our first set of simulations was carried out to investigate the performance of the proposed test when all chromosomes were identical in length.
