BIOL 344 Lecture Notes - Lecture 18: Mendelian Inheritance, Genetic Linkage, Gamete
Document Summary
Gene is closer together, probability of recombination is diminished and number of recombinant is diminished one map unit = 1% recombinants. Genetic map units do not equate or convert directly to any physical distance. Genetically linked two genes are less than 50 mu. Anything more than 50 mu, they are independently assorted, thus half half. Why is 50mu the magic number in genetics. Two genes that are equal to or more. Above 25 mu, lose accuracy because gets multiple crossover a. Multiple crossover looks for parental thus lower the possibility. What is happening between stage 1 and stage 2. At what stage, of what process does 2 occur. Any number and arrangement of co will result in 50% recombinant gametes on average when multiple meiosis are considered. Double crossovers happening between gene a and gene b. Two cross over btwn the same nonsister chromatids = no recombinant. Three-strand double cross over all likely to happen.
