Document Summary
Chapter 3. 6: the chromosome theory of inheritance and sex chromosomes. Chromosome theory of inheritance: came around due to three main discoveries. Mendel"s studies transmission of traits from parents to offspring. N geli"s studies substance found in living cells is responsible for the transmission of traits from parents to offspring, and both parents contribute an equal amount. Hertwig, strasburger and flemming chromosomes are the carriers of the genetic material: two scientists independently came out with the origins of the chromosome theory of inheritance. Walter sutton at columbia university, and theodore boveri, a german biologist. Sex chromosomes: because there are many genes on the x chromosome that are not on the y chromosome, geneticists were able to figure out which certain traits come specifically with sex chromosomes. The study was done largely with fruit flies: x-linked inheritance. Confirmed the idea that genes are found on chromosomes.
