IMMENSE PROBLEM SOLVING. "Polyploidy with odd numbers of chromosome sets poses an even greater problem because aneuploid gametes are generally produced. However, there are some plant species where solutions to even this problem have evolved and odd-number polyploidy appears to persist stably." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

SONG OF DARWIN. "The more I study nature, the more I become impressed […] that the contrivances and beautiful adaptations [acquired through natural selection] transcend in an incomparable degree [those] which the most fertile imagination of the most imaginative man could suggest with unlimited time at his disposal." http://www.sciencedirect.com/science/article/pii/S0960982214003881 View in LinkedIn

TRANSITION MECHANISM. "Part of the answer seems to be a reduction in the number of COs, since multivalents can only form with at least two COs per chromosome. There is also mounting evidence for genes that have been selected to control pairing behaviour of chromosomes during meiosis, such as ph1 in hexaploid wheat and several candidate genes in polyploid." Arabidopsis." (CO = cross-overs). https://lnkd.in/e2tp_G5 View in LinkedIn

TRANSITION. "Meiosis and syngamy represent critical transitions between haploid and diploid phases in each generation." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

NO PLANT ARRESTS. "Meiotic arrests in plants are unknown. Plants seem to completely lack strict mechanisms to arrest the meiotic cell division. Contrary to animals and fungi that for example arrest the cell cycle and abort meiosis once double strand breaks are not repaired, plants will progress through meiosis irrespective of such major defects." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

MEIOTIC ARRESTS. "Whereas male meiosis occurs continuously, female meiosis usually stops twice." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

GERMLINE. "In animals, where haploid mitosis is suppressed, syngamy immediately follows meiosis. Furthermore, specific cells are ‘destined’ at an early stage to eventually undergo meiosis (a.k.a germline), whereas this cell fate is determined much later in fungi, plants and some algae." https://lnkd.in/e2tp_G5 View in LinkedIn

SOMATIC CONTROL. "In metazoans, life cycles are mostly determined by the extent of somatic development within each phase rather than by the timing of meiosis, which can be halted or postponed." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

CELLULAR BOTTLENECK. "In multicellular eukaryotes, where meiosis is tightly associated with reproduction (unlike in many protists), meiosis is also a cellular and genetic bottleneck at the critical transition between the diploid and the haploid phases." https://lnkd.in/e2tp_G5 View in LinkedIn

CORE TO BOTH PATHWAYS. "Meiosis is a key step in sexual life cycles, as well as some asexual life cycles derived from sexual ancestors." https://lnkd.in/e2tp_G5 View in LinkedIn
