In ivies, however, polyploidy played a major role in speciation.
Another study demonstrated that new species offreshwater snails had arisen due to polyploidy.
High polyploidy(large number of copies of each chromosome category).
It turns out that speciation in quite a few plants is based in part, at least, on polyploidy.
Does polyploidy confer an advantage to animals, is it neutral, or is it disadvantageous?
It is a tetraploid species,leading to the possibility that multiple rounds of polyploidy occurred during the speciation process.
Polyploidy arises as part of reproduction, generally as a reproductive error.
With all these polyploid animals that we know exist in the world,it is logical to ask whether polyploidy is a blessing or a curse.
Polyploidy would have created new species rapidly, even in the evolutionary paradigm.
Since an increase of information is needed for molecules-to-man evolution,evolutionists postulate polyploidy as a means for this.
Polyploidy is at least one extra copy at every paired chromosome in the genome.
They come in tetraploid and diploid variants, and according to evolutionary phylogeny,multiple lineages have resulted in polyploidy.
Polyploidy is thus not an evidence for evolution or an increase in actual information.
A study done on these creatures suggested that the two genera underwent polyploidy at least four times in Xenopus and twice in Silurana.
It would seem that polyploidy cannot be as deleterious in animals as was once believed.
While these numbers are undoubtedly high, since they are often based on a universal common ancestor for plants,there is consensus in the literature that plant polyploidy is a common occurrence.
Maintaining polyploidy relies on the reproductive success of the newly polyploid organisms.
Polyploidy is important to scientists because it produces reproductive isolation, almost by default.
It should be noted the polyploidy observed in pathological conditions(growth of malignant neoplasms).
Polyploidy, though less common in animals than it is in plants, does appear to have played a role in the speciation in animals.
Yarrows are another group where polyploidy played a major role in forming the existing species and did so rapidly.
Since polyploidy has been known to be common and is purportedly beneficial in at least some plant species, this first paper will focus on plants.
It has been argued for decades that polyploidy is relatively uncommon in animals, though this has been challenged in recent years.
However, polyploidy does not always result in reproductive isolation, as some researchers studying the mustard family discovered in 2008.21.
Despite its prevalence, Mayr regarded polyploidy as problematic rather than a simple, straightforward speciation event:“Polyploids pose a difficult taxonomic problem.
Polyploidy special role in the processes of normal differentiation of certain cells in the individual development(ontogenesis) higher plants and animals, including humans.
This and the next paper from this author will discuss whether polyploidy is deleterious, give examples of polyploid organisms, and attempt to explain polyploidy in a biblical creation paradigm, while assessing whether it is a viable mechanism for evolution.
If polyploidy were created in an original baramin, we would expect that a sizeable majority of the baramin would exist in a polyploid state today.
If polyploidy were created in some of the original created kinds in Genesis 1, it would be expected that a sizeable majority of a given baramin would exist in a polyploid state today.
