VIII. Recognition of Mendel’s work came during the early 20 th century He published his results in 1866. A. Gametes and fertilization were known at the time but mitosis and meiosis wasn’t. He formulated them through mathematical principles. B. Biologists Sutton and Boveri pointed out Mendel’s segregation of alleles and the separation of homologous chromosomes during meiosis a. Chromosome theory of inheritance or Sutton-Boveri theory- states that inheritance can be explained by assuming genes are linearly arranged in specific locations along the chromosomes i. Geneticist Morgan provided location of white eye color on the X chromosome in fruit flies IX. Using Probability to Predict Mendelian Inheritance A. Genetic ratios expressed in probabilities

Unformatted text preview: a. Expected ratio of dominant and recessive phenotypes is 3:1= probably is frequency chance that any individual offspring of heterozygous individuals will express dominant phenotype chance that any individual offspring of heterozygous individuals will express recessive phenotype B. Event is certain to occur = probability is 1 Event is certain NOT to occur= probability is 0 A probability can be 0,1, or some number between 0 and 1 C. Punnett Square following two statistical principles a. Product rule- predicts the combined probabilities of independent events. Events are independent if the occurrence of one does not affect the probability the other will occur....
