Document Summary

Chromosome theory of inheritance: mendelian genes have specific positions along chromosomes, and it is the chromosomes that undergo segregation and independent assortment. Law of independent assortment: alleles of genes on non-homologous chromosomes assort independently during gamete formation. Law of segregation: the two alleles for each gene separate during gamete formation. Lecture 8 intro to evolution: also, changes in genetic composition of population from gene to gene. Aristotle: viewed species as fixed, recognized certain affinities among organisms considered that life forms could be arranged on a ladder (complexity) Ideas were consistent with the old testament species were created by. Linnaeus: developed 2-part format for naming species, also, developed classification for species. Lamarck: explained his finding using 2 principles: Idea that parts of the body that are used become stronger, while those that are not used deteriorate. Organisms can pass these modifications to its offspring: also, thought that evolution occurs because organisms had an innate drive to become more complex.
