BIOL 3301 Genetics Exam III QUESTIONS & ANSWERS 100% ACCURATE!
How can we determine genotype frequencies at some gene A? - ANSWERS1. Collect organisms (you go out and set traps for instance, like maybe this weekend) 2. Separate organisms according to their genotype AA, Aa, aa. (obviously you have to be able to tell them apart somehow, either visually or by sequencing techniques) 3. Divide the number of each genotype collected by the total collected Example: AA is 78 Aa is 20 aa is 2 Genotype Frequency (AA) is 78/100 = 0.78 Genotype Freque...
