Document Summary
Domestication and selective breeding (8-1000 bc) to manipulate the genetic material of. Theory of epigenesis: (william harvey) organism develops from fertilized egg, develops egg into adult. Cell theory: (shleiden. /schwan) cells come from preexisting cells. Spontaneous generation: things come from non living things. Darwin: hms beagle voyage, descent with modification, theory of natural selection. Mendel: peas ( traits passed down from parent to offspring) Mitosis: daughter results is diploid chromosomes (2n) identical to parent cell. Meiosis: da km 8m8888900ughter results in half haploid number (n) of chromosomes. Chromosome theory of inheritance: (walter sutton & theodor) inherited traits are controlled by genes on chromosomes, results in genetic continuity from gen to gen. Genotype: set of alleles for a trait. Ex: drosophila melanogaster (fruit fly) is white eyed. Has genetic variation bc of mutation in gene controlling eye color (allele) Dna, not protein has genetic info ( avery, macleod, mclean, mccarty) Dna structure (watson and crick) double helix strand made of atgc.
