Cross over is the first way genes are shuffled to give rise to genetic diversity. Cross over takes place in sexual reproduction. The normal way that cross over occurs is chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other.
If they break the pieces at the same locus in the sequence of base pairs, the result is an exchange of genes called genetic recombination and it ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity occurs.
Answer:
natural selection acts directly on an organism's phenotype.
In a fox population the allele frequency for red fur changes from 20% to 30%. This means that the fox population is evolving.
If two eukaryotes participate in lateral gene transfer, what will this do to the overall genetic variation of the species? The genetic variation will increase.
Genetic recombination includes the independent movement of chromosomes during meiosis as well as crossing over.
Three sources of genetic variation are sexual reproduction, lateral gene transfer, and mutations.
