LIFESCI 7B Lecture Notes - Lecture 6: Meiosis, Mitosis, Chromosome
Document Summary
Meet a mold: neurospora crassa neurospora"s reproductive life cycle meiosis then mitosis. After meiosis produces 4 halpoid cells, mitosis then turns these into 8 haploid spores grow mold and vegetatively through mitosis. Neurospora spores line up the way that nuclei separated during meiosis 1 and 2 two coming together, the rst division, second division of meiosis, then the mitotic division. Week 3: genetic and environmental basis of complex traits. Explain how genetic distance is di erent from physical distance on a chromosome. Explain why the measured recombination frequency between any two genes is never greater than 50% Explain the terms snp, vntr, rflp, and genetic marker. Explain and discuss how various factors might in uence the relationship between genotype and phenotype. Explain how non-disjunction, recombination, and gene by environment interactions can complicate pedigree analysis. Describe how variation can be measured and what can be done to distinguish genetic and environmental sources of variation.
