LIFESCI 7B Lecture Notes - Lecture 10: Allele Frequency, Mendelian Inheritance, Genotype Frequency
Document Summary
Calculate expected genotype frequencies in a population given allele frequencies. Independent assortment leads to gametic diversity without recombination a human can produce 8. 4 million (2 ) di erent kids of gametes for every couple, there are 7. 04x10 possible combinations. Malaria is a pathogen that infects red blood cells during part of its life cycle. Natural selection acts on phenotype not really genotype. In an environment where malaria is common, which genotype has the highest tness: a1a1 || b. a1a2 || c. a2a2 in an area where malaria is common, individuals who are a1a1 may die from malaria. A2 can deal with malaria better bc malaria attacks bi concave rbc"s and the sickle cells can still carry little oxygen in the blood and malaria does not attack those cells. ****know the di erence between balancing and stabilizing selection bc they are not the same***
