Document Summary
Remember darwin had no understanding of genetics and inheritance mechanisms genotype: genetic makeup of an organism - used in relation to a specific gene or gene combos. Phenotype: physical appearance of organism that can be observed - used when discussing traits or features of organisms. Genome: the entire dna set of an organism including genes and non-coding regions. The gene is a complex concept; has slightly varying definitions o o o. A dna sequence composed of codons essential for a specific biological function. Evolution requires genetic variation which comes from o o o o. Mutation is the ultimate source of genetic variability on the planet. It is a fundamental process as it generates genetic variability. Mutation rates are very low therefore new genetic diversity comes from recombination. An enormous amount of genetic diversity comes from recombination, much larger than mutation supplies, comparatively. Mutation is more of a long term ongoing process.
