WebPolyploids are considered a new species because the occurrence of a whole genome duplication imposes post-zygotic barriers, which enable reproductive isolation between parent populations and hybrid offspring. Polyploids can arise through single step mutations or through triploid bridges.

WebA species is a group of organisms able to interbreed and produce fertile offspring. New species can arise as a result of the following things: genetic variation - each population … WebEvolution by natural selection occurs when certain genotypes produce more offspring than other genotypes in response to the environment. It is a non-random change in allele frequencies from one generation to the next.
WebNew alleles originate by mutation, a permanent change in the nucleotide sequence of DNA. Mutation is the ultimate source of the genetic variation that serves as raw material for evolution. In multicellular organisms, however, only mutations in cells that produce gametes can be passed to offspring and affect a population ' 3 genetic variability. WebMar 15, 2024 · 1 INTRODUCTION. A growing body of work in experimental evolution, spurred by Stephen Jay Gould's idea of “replaying life's tape”, has begun to evaluate whether evolution follows a deterministic route in response to some environmental pressure (reviewed in Blount et al., 2024; Lobkovsky & Koonin, 2012; Losos, 2024).The question …
