Document Summary
Models for the origin of homo sapiens. Only way to show it is genetics. Gene = section of dna with effect on phenotype. Allele = alt version of a gene. Phenotype = observable properties of an organism. Quantitative: how genes are passed down in families. Developmental genetics: how genes are expressed in development. Population genetics: study of allele frequencies in and between populations. Genomics: statistical analysis that comapre large sequences of dna. The complete set of chromosome"s dna sequence. We have 46 chromosomes, 23 pairs - 23 from dad, 23 from mom. 23 pairs in humans, 24 in chimps. Sperm and egg cells may have of the set of chromosomes so we have. Gametes are the cells in your body that form sperm or egg cells -- the germ lines. 3 billion chemical base pairs that make up human dna. Francis collins - wrote language of god. Involved in human genome project - cost 2. 7 billion.
