PPT-How to alter the alleles in a population

Natural Selection Definition A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits Stresses from the environment creates situations where the organisms with a beneficial trait will survive and reproduce those without will die off. Module 2: Inbreeding. Genetic Diversity. A few definitions. Small Populations. Random drift. Changes in variance, genotypes. Mating Systems. Inbreeding coefficient from pedigrees. Coefficient of coancestry. 8.5. Starter. What is the term for all the alleles of all the genes in a population?. Gene Pool. What do you think the term would be for the number of times an allele occurs within a gene pool?. Allelic Frequency. Cardboard Cut Out. Essential Questions. Who am I?. Who do I want to be?. Challenge:. Create a life size cardboard cut out of your alter ego.. You may use whatever two dimensional materials you would like to create your project.. Gene and Genotypic frequencies. The Hardy Weinberg law states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences..
