But Prime is just one of Amazonâs subscription businesses, which now include offerings like Subscribe & Save, Amazon Instant Video, Amazon Mom and Amazon Web Services. This explosion of the subscription business model has led to a spike in mergers and acquisitions activity. Witness Facebookâs $19 billion acquisition last year of the subscription-based messaging platform WhatsApp or Charles River Ventureâs recent investment of $4 million into subscription-box company Cratejoy.
Random Chromatid Assortment. A third source of genetic diversity occurs during meiosis II, in which the sister chromatids separate and are randomly distributed to the daughter cells, the gametes. Crossing over in meiosis I leads to non-identical chromatids in meiosis II chromosomes.
Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species. It is distinguished from genetic variability, which describes the tendency of genetic characteristics to vary.Genetic diversity serves as a way for populations to adapt to changing environments.With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele.iversifying selection is the hypothesis that two subpopulations of a species live in different environments that select for different alleles at a particular locus. This may occur, for instance, if a species has a large range relative to the mobility of individuals within it.
