Population Genetics and Evolution Within a Gene Pool INTRODUCTION: The Hardy-Weinberg scheme is a way of viewing evolution as changes in the frequency of alleles in a population of organisms. If A and a are alleles for a particular gene and each individual has two alleles then p is the frequency of the A allele and q is the frequency of a alleles. The frequency of the possible diploid combinations is expressed in the equation p2+2pq+q2=1. In order for the Hardy-Weinberg equation to work five conditions

CHAPTER 1 1.0 INTRODUCTION Students’ Industrial Work Experience Scheme (SIWES) is a skill development program designed to prepare students of Universities‚ Polytechnics/monotechnics and colleges of education for transition from the college environment to work (Akerejola 2008). Oyedele (1990) state that work experience is an educational program in which students participate in work activities while attending school. 1.1 brief histories of SIWES The Students’ Industrial Work Experience Scheme (SIWES)

Modulation FM [3]Frequency modulation (FM) is a method of impressing data onto an alternating-current (AC) wave by varying the instantaneous frequency of the wave. This scheme can be used with analog or digital data. Frequency modulation is similar in practice to phase modulation (PM). When the instantaneous frequency of a carrier is varied‚ the instantaneous phase changes as well. The converse also holds: When the instantaneous phase is varied‚ the instantaneous frequency changes. But FM and

SIMULATION OF NATURAL SELECTION MATERIALS Plastic or paper bag containing 100 beads of two colours additional beads as needed. AIM To prove that both allele and genotype frequencies in a population would not remain constant if natural selection occurs. Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. INTRODUCTION Natural selection‚ the differential survival and reproduction of individuals was first proposed by

The Hardy Weinberg principle states that the allele and gene frequencies will stay constant from generation to generation as long as no other evolutionary influences come along. The evolutionary influences can be things such as mutation‚ mate choice‚ selection‚ genetic drift‚ gene flow‚ and meiotic drive. Frequency is the proportion of individuals in a certain category relative to the total number of individuals considered. The frequency of an allele or genotype is expressed as a decimal proportion

along with natural selection‚ mutation‚ and gene flow‚ is one of the basic evolutionary forces of evolution. Evolution is the method by which allele frequencies in a population change over time. This process can be random‚ where the changes occur through genetic drift (Hahn and Bentley 2003). Genetic drift causes these random changes in allele frequencies‚ which result from random fluctuations across generations. Genetic drift happens in ALL populations‚ large and small‚ but affects them to a different
