LIFESCI 1 Lecture Notes - Lecture 3: Genotype Frequency, Mustard Plant, Microevolution
Document Summary
Microevoluion- a change in the relaive frequencies or alleles or genotypes in a gene pool over ime. Produces 4 (haploid) daughter cells; each daughter cell has # of chromosomes as parent cell. The combinaion of genes within each haploid either a sperm or an egg is geneically disincive. Mitosis in my toes deals with making skin cells and growth; meiosis in my ovaries deals with making eggs. Since each gene may be passed on independently, there are 8. 4 million diferent gametes, and with someone else, becomes 7 ee 13 (scieniic notaion) diferent combinaions. Homozygous dominant or homozygous recessive or heterozygous. Populaion geneics- first igure out the allele frequency of a populaion. Hardy-weinberg equilibrium- this is how to ind genotype frequency (p 2 + 2pq + q2 = 1). With this, you may determine if a populaion is evolving or not; if there is evoluion, you cannot get the future answer.
