1. Genetic diversity

   Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species, it ranges widely from the number of species to differences within species and can be attributed to the span of survival for 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. The population will continue for more generations because of the success of these individuals.The academic field of population genetics includes several hypotheses and theories regarding genetic diversity. The neutral theory of evolution proposes that diversity is the result of the accumulation of neutral substitutions. Diversifying 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. Frequency-dependent selection is the hypothesis that as alleles become more common, they become more vulnerable. This occurs in host–pathogen interactions, where a high frequency of a defensive allele among the host means that it is more likely that a pathogen will spread if it is able to overcome that allele.

Examples of genetic diversity in a Sentence

1. Ronald Swaisgood:

   Pairs are selected to maximize maintenance of genetic diversity in the panda population. This is essential for maintaining healthy populations, and currently we have no problem with this, however, there are often several candidate mates that are genetically suitable, and we believe that behavior and mate choice has a role to play for improving the success rate of breeding among genetically suitable partners.

2. Craig Hilton-Taylor:

   Losing these plants would reduce the genetic diversity of tea.

3. Marc Haber:

   Our findings give us an unprecedented view of the ancestry of the people who fought in the Crusader army. And it wasn't just Europeans, we see this exceptional genetic diversity in the Near East during medieval times, with Europeans, Near Easterners, and mixed individuals fighting in the Crusades and living and dying side by side.

4. Robert Garry:

   If these sequences were removed for the purpose of obscurity, it is also worth noting that such an effort clearly flopped because... these sequences do not immediately provide any completely new knowledge about the genetic diversity of SARS-CoV-2 in the early pandemic, the reality is that minor scientific missteps and less-than-ideal circumstances surround the sharing of scientific data all of the time.

5. Bence Viola:

   These Denisovans who were all found have twice as much genetic diversity as Neanderthals and close to as much genetic diversity as we see in modern humans, which is pretty surprising.
