Document Summary
Test over material that is covered in class (fair game) Genetics is very basic so focus in lecture not what s in the text book. Not survival of the fittest, this misses two things: variation is critical, but also consider the environment. A trait that was advantageous in the past may not be later. Modern synthesis = darwin s theory of natural selection (operates on phenotype) and. If adaptive traits tend to succeed, this would reduce variation. Sources of variation: recombination and assortment of chromosomes, chromosomes (parents genotype) can be sorted 8x106 different ways, crossing over (recombination?, mutations. Example of sorting marbles & 6 fingers in older amish population (isolated population) Exchange of genetic material between populations through direct or indirect breeding that distributes variation. Sleeping with one person is like sleeping with everyone they have slept with . Looking alike and being close not the same thing. There is no question that individual human beings are different.
