Evolution Test Notes Giulia Palazzo • THE HARDY- WEINBERG PRINCIPLE: - a mathematical equation created to predict genotype and phenotype frequencies in a population that is not experiencing any selective pressure‚ if model fails evolution must be occurring - Under Mendel’s model‚ the two alleles can be represented by... p + q = 1 (100% of the alleles in the population) where p is the dominant allele and q is the recessive allele - The genotypes can be represented by the equation (p+q)² = p² + 2pq

Evolution and Classification Test Darwin/Lamarck Darwin’s observations: Usually the numbers of offspring produced are far greater than the ones that survive Natural resources are limited. This leads to a struggle for existence with only a fraction of offspring surviving to the next generation Slight variations (mutations) occur by chance within a population These variations are inheritable Darwin concluded that living organisms were evolving through

trait is the effect caused by the interaction of different genes. Blood pressure is not the result of a single gene. The phenotype is a mixture of a person’s weight‚ metabolism‚ etc. Each of these factors have multiple alleles. d. Hardy-Weinberg equilibrium is an important approach for predicting the dynamic s in allelic distribution. It uses 4 assumptions. List those assumptions and explain for each of them‚ why they are unattainable in real life. You can organize your answer as a table.

migration as tools to understand how and why populations undergo changes in allele and genotype frequencies‚ as well as its effects for future generations. To recognize the effects of genetic drift on a population‚ an understanding of the Hardy-Weinberg Equilibrium must be met. This theory states that if certain conditions are met there will be no evolution occurring in a population. Simply put‚ if a population is in HWE‚ then that population is not evolving‚ and you can expect the population to stay

alleles Total = ___64___ A alleles q = Total number of A alleles / Total number of alleles in the population = 64/160 = _0.40_ Case I Questions 1. What does the Hardy-Weinberg equation predict for the new p and q? It predicts that the new p and q will be determined by a chance rather than it being picked. 2. Do the results you obtained in this simulation agree? If not‚ why? No the results do not agree because
