WebMar 10, 2013 · 6. Speciation can occur by polyploidy. My understanding of the process is as follows: 'polyploidy is when the number of chromosomes in an organism's cell doubles. This means that the organism has more chromosomes than other individuals of the same species, meaning it cannot mate with other individuals. The polyploidy organism then … WebD2 Species and Speciation. D.2.1 Define allele frequency and gene pool. Allele Frequency: The proportion of an allele within a population.

WebThe definition of species as a group of individuals whose members have the potential to interbreed and produce viable, fertile offspring is known as the biological species concept. Inherent in this concept of species as populations of reproductively compatible individuals is the related concept of speciation as dependent on reproductive isolation.

WebIn parapatric speciation there is no specific extrinsic barrier to gene flow. The population is continuous, but nonetheless, the population does not mate randomly. Individuals are more likely to mate with their geographic neighbors than with individuals in a different part of the population's range. In this mode, divergence may happen because of reduced gene WebThe PowerPoint presentation discusses the definition of a species, how species are isolated (prezygotic & postzygotic), and how new species are created (allopatric and sympatric speciation).

Sympatric speciation can occur through errors in meiosis that form gametes with extra chromosomes (polyploidy). Autopolyploidy occurs within a single species, whereas allopolyploidy occurs between closely related species.

WebTypes of Speciation. Speciation can take place in two general ways. A single species may change over time into a new form that is different enough to be considered a new species. This process is known as anagenesis. More commonly, a species may become split into two groups that no longer share the same gene pool.
