Document Summary

Character: a heritable feature that varies among individuals. e. g. eye colour. Trait: a variant of a particular character. e. g. blue eyes: traits are not inherited directly, the appear during development p. 180. Determines a characteristic in organism http://jonesgen564s14. weebly. com/flnb-gene. html: the expression of genes, along with environmental factors, determine the traits observed. p. 83,182. Allele: a version of a gene character traits gene alleles p. 182 eye: rebelcircus. com chromosome: broadinstitute. org. Gregor mendel: mendel was a monk in brno in the 1860s. Studied mathematics, physics and chemistry: interested in how traits are inherited, chose garden peas (pisum sativum) for his inheritance experiments p. 180. Reproduction can be controlled: self- or cross-fertilise, both parents known p. 180. When 2 identical true-breeding individuals are crossed, all offspring have the same characteristics as the parents. Using true-breeding pea varieties allowed him to study the inheritance of one trait at a time pp. 180-183. Mendel: methods: mendel crossed two different true-breeding varieties together.
