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.
WebPolyploidy is a condition in which the cells of an organism have more than one pair of ( homologous) chromosomes. Most species whose cells have nuclei ( eukaryotes) are diploid, meaning they have two complete sets of chromosomes, one from each of two parents; each set contains the same number of chromosomes, and the chromosomes are joined in ... WebWhat is Autoploidy and Alloploidy? Aneuploidy is the presence of an abnormal number of chromosomes in a cell. There is an extra chromosome present in this case. Polyploidy is the presence of the extra set of the chromosome in the cells. There is a complete new set of the chromosome present. All the given conditions are the cases of aneuploidy.
WebAneuploidy: Extra or missing chromosomes. Changes in a cell's genetic material are called mutations. In one form of mutation, cells may end up with an extra or missing chromosome.
