Document Summary
Data collected from observations or from experiments allow to test hypothesis. The chi-square test: allows us to determine whether observed values differ from elected values, x^2= (observed-expected)^2/ expected, determines degrees of freedom: observed - 1, if x^2 > critical value: reject hypothesis. Square = male coloured in circle/squre = individuals without trait. Q= [n/(x)(y)] p^x q^y n = number offspring x = # unaffected y + # affected p = probability of unaffected q = probability of affected. Genetic counselling: a bene t of analyzing human pedigrees is that parental counselling may be provided to assess the risk of having a child with genetic condition. Chromosomes: each species has a characteristic set of chromosomes: autosomes (non sex chromosomes) and sex chromosomes. Heterochromatin: more condensed, high in at, stain darker. Chromosome theory of heredity: thomas hunt morgan: meiotic behaviour of chromosomes is the basis of mendel"s principles of segregation and independent assortment.
