Document Summary
Genetics: how are traits inherited: a typical genetic observation, a trait is existent from the 1 st generation and disappears in the 2 nd generation, but may appear, this suggests that traits are not inherited per se. However, elements that determine the traits in the third generation are inherited. Short generation time: because there are clearly defined traits, can select breeding partners, large numbers. Self-fertilized offspring fertile: mendel"s methods, tests of true breeding: self-crossing. Traits examined by mendel: round vs wrinkled, yellow vs green, lots of different traits, mendel found from his mono-hybrid crosses : 3:1 ratio was commonly seen in f2 generation for many characters. Testcross: to distinguish individuals with pp vs. pp genotypes, detects heterozygotes by crossing a dominant phenotype (allele distribution unknown) with, cross dominant phenotype to homozygous recessive homozygous recessive (known genotype) If start off with pp, then all offspring would be purple and heterozygotes.
