What does meiosis have to do with genetic diversity ?

Genetic variation is increased by meiosis. During fertilisation, 1 gamete from each parent combines to form a zygote. Because of recombination and independent assortment inmeiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.

Crossing Over. During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis(which reshuffles alleles within an organism's offspring).

Meiosis is sex cell division, sex cells mainly being genes. When the father or the mother have dominant allele the child gets the same allele but with a recessive allele too.
For the second generation, this difference in phenotype and genotype will cause a clear genetic diversity. The same continues for the rest generation too.

The scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world. it involves making observations, formulating a hypothesis, and conducting scientific experiments.the steps of the scientific method are •observation-the first step of the scientific method involves making an observation about something that interests you•question-once you've made your observation, you must formulate a question about what you have observed. •hypothesis-once you've made your observation, you must formulate a question about what you have observed. •experiment-once you've developed a hypothesis, you must design and conduct an experiment that will test it.•results-the results are where you report what happened in the experiment. •conclusion-the final step of the scientific method is developing a conclusion.i hope that this you : )

Centration is the correct answer
