Document Summary
Why study genetics: genetics plays a critical role in understanding disease, genetics improves agricultural practices, genetics in drug design, development & production. Outline: define, recognize and apply mendel"s first principle, distinguish genotype and phenotype, solve genetic problem relating to monohybrid crosses. Interpret pedigrees: assess mode of inheritance, assign genotypes, use the rules of probability to determine genotypic and phenotypic proportions. Take home problem 1: an albino child can be born only if the two parents are heterozygous carriers of recessive allele, probability for the other parent to be heterozygous is 2/3 aa and 1/3 aa. If both parents are heterozygous, the probability of an albino child is 1/6: 1 aa (father) * 2/3 aa (mother) * 1/4 aa (child) Take home problem 2: you have a plant with a wild-type phenotype, but genotype is unknown, describe an experiment that will determine the genotype (aa, aa, or aa)
