CURIOUS CASE. "Sexual organisms produce haploid gametes derived from meiosis. Fertilization of the egg by the sperm restores the chromosome number to that of the somatic cells. However, certain factors can lead to the formation of unreduced gametes, in which the genetic material is identical to that of somatic cells, in some cases specifically in females." https://lnkd.in/eWhHmsj View in LinkedIn

INCOMPLETE PROCESS. "Whole genome duplication is considered to be a significant contributor to angiosperm speciation due to accumulation of rapid, strong interploid reproductive isolation. However, recent work suggests that interploid reproductive isolation may not be complete, especially among higher order cytotypes." https://lnkd.in/eyABWAW View in LinkedIn

ALTERNATION OF GENERATIONS. "Plants have a more complex life cycle than animals, alternating between two heteromorphic generations: the sporophyte and the gametophyte. In the diploid sporophyte, distinct cells undergo meiosis and produce haploid spores. These give rise to multicellular haploid gametophytes, which produce gametes through mitotic divisions."

PLOIDY FROM MALFUNCTION. "Speciation and diversification of plants has been attributed, in part, due to polyploidy otherwise known as whole-genome duplications (WGD). Changes in ploidy can result from aberrations in meiotic or mitotic processes, which includes whole genome duplications." https://lnkd.in/etn6Uea View in LinkedIn

ANGIOSPERM PLOIDY. "There is a high level of biodiversity in angiosperms that indicate plants have undergone extensive diversification. Some of this diversity, on the genomic level, can be explained by a high degree of variation in ploidy level and/or chromosome number." https://lnkd.in/etn6Uea View in LinkedIn

PLASTICITY IMPACT. "The interplay between phenotypic plasticity, ecology and evolution is further complicated by the fact that the plasticity of one trait can influence the phenotype of another, later in the developmental trajectory or in the life cycle of a species." https://lnkd.in/dN4mKjm View in LinkedIn

MULTIPLE PHENOTYPES. "If one plastic genotype can result in various phenotypes, the emergence of alternative genotypes becomes unnecessary. Additionally plasticity can hide genetic diversity since one (optimal) phenotype can originate from multiple genotypes (canalization)." https://lnkd.in/dN4mKjm View in LinkedIn

CONTRASTING POSITIONS. "It has been argued that increased plasticity enables the appearance of new phenotypes and thus promotes diversification, population divergence and speciation. Conversely, it has also been put forward that plasticity can prevent diversification." https://lnkd.in/dN4mKjm View in LinkedIn
