Immigration, mutation and sexual reproduction.
Genetic variation, which can lead to evoloution, and then potentially a new species.
If a population dwindles, there is low genetic variation and a species may risk extinction.
Hybrid
genetic variation happens because of meiosis. chromosomes are randomly in each sperm/egg cell, and so when they come together it's unlikely to get the same combination twice
The result of crossing over is genetic diversity. More specifically, it is a hybrid chromosome with a unique pattern of genetic material. Does this answer help?
the shuffling of genetic material through sexual reproduction, which introduces new combinations of genes and increases genetic diversity in offspring. In contrast, asexual reproduction produces identical offspring through mitosis, resulting in less genetic variation within the population.
Genetic variation, which can lead to evoloution, and then potentially a new species.
Variation within a species is due to genetic diversity, which arises from random mutations, recombination during reproduction, and gene flow from other populations. This variation provides the raw material for natural selection and enables species to adapt to changing environments.
Sexual reproduction typically results in a wide range of variation in species. This is because it involves the mixing of genetic material from two individuals, leading to the expression of different traits in offspring. This variation can help populations adapt to changing environments and increase overall genetic diversity.
Two key factors that determine the evolution of a species are genetic variation and natural selection. Genetic variation provides the raw material for evolutionary change, while natural selection acts on this variation by favoring individuals with traits that increase their chances of survival and reproduction.
Gentic variation is mearsured by the number of species in the given area not.
Variations occurs in species due to the process of "Crossing over"
The bacterial species that produces Deoxyribonuclease is Staphylococcus aureus. It is an enzyme that helps the bacteria break down DNA, allowing it to acquire genetic material from its environment.
If a population dwindles, there is low genetic variation and a species may risk extinction.

The process of crossing over during meiosis increases genetic variation within a species by shuffling genetic material between homologous chromosomes. This genetic diversity enhances the ability of a species to adapt to changing environments and increases the likelihood of beneficial traits being passed on to offspring. Ultimately, this can improve the species' chances for survival and successful reproduction.
The genetic variation of a population is a measure of how much individuals in a population differ genetically.
