Document Summary
Microevolution heritable variation in genetics of a population. Population individuals of a single species living together at the same time and place. Phenotype variation heritable variation in appearance and/or function. Width of a variation graph is proportional to the amount of variation. Phenotype is not always correlated with a genotype. Only these are subject to evolutionary change. It is often testable to see which of is influencing the phenotype by changing the environment and see if the individual responds. If artificial breeding is experimented with, only the genetic variable traits will be passed on to future generation. Ex: the distance/speed ran by mice in an artificial breeding experiment. Recombination (meiosis crossing over/independent assortment, random fertilization) Discovered that half of all loci are polymorphic. It underestimates the actual value of possible genetic variance. Also take a look at the chromosomal and mitochondrial dna. Gene pool sum of all alleles at all loci of all individuals within a population.
