It mixes the chromosomes of the two parents
A lack of genetic variation in a species can be caused by factors such as inbreeding, habitat fragmentation, or a population bottleneck, where a significant portion of the population is suddenly reduced. This reduced genetic diversity can lead to increased susceptibility to diseases, reduced adaptability to environmental changes, and a higher likelihood of extinction. Over time, the lack of variation may result in decreased overall fitness and resilience of the species.
the cell goes through mitosis (interphase, metaphase, anaphase, telophase) and it splits into two identical cells (during this process the DNA is duplicated). As a result of asexual reproduction, there is no variation in population.
If a species has homologous chromosomes, it means that they have pairs of chromosomes with similar genes in the same order. This can facilitate genetic diversity through processes like crossing over during meiosis. Homologous chromosomes are essential for genetic variation and proper segregation of genetic material during cell division.
Low Genetic variationis the raw material of evolution. Without genetic variation, a population cannot evolve in response to changing environmental variables and, as a result, may face an increased risk of extinction.

No, adaptations usually do not result in any genotypical change in a species.

Genetic drift, founder effect, and population bottlenecks are mechanisms that can decrease genetic diversity in a species. These mechanisms result in a reduction of variation within a population due to random events that affect the genetic makeup of the population.
Sexual reproduction leads to variety in offspring.
Genetic variation in bacterial populations cannot result from sexual reproduction, as bacteria typically reproduce asexually by binary fission.
