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 of the total alleles or genotypes

The Hardy-Weinberg theorem states that the frequency of alleles and genotypes in a population’s gene pool remain constant over the generations unless acted upon by agents other than sexual recombination. For example‚ take a population of mice that consists of 1‚000 members. A specific allele‚ albino allele‚ is recessive within this species. 80% of the population expresses the normal phenotype- brown coloring‚ while the remaining 20% are albino. 640 members of the population have the genotype AA‚

importantly new alleles (a number of alternate forms of the genetic pool) to enter the population. By having different genetic combinations‚ those of a population reveal different traits which may or may not be to their benefit‚ in respects to their social and environmental interactions or surroundings. Because of the genetic variation‚ certain qualities maybe preferred over others influenced by given surrounding and as a result change the allelic frequency towards the favoured allele However

Calculate‚ showing all work‚ the frequencies of the alleles and frequencies of the genotypes in a population of 100‚000 rabbits of which 25‚000 are white and 75‚000 are agouti. (In rabbits the white color is due to a recessive allele‚ w‚ and agouti is due to a dominant allele‚ W.) C. If the homozygous dominant condition were to become lethal

Discussion: Referring to the hypothesis we predicted in the beginning of this experiment that under ideal conditions‚ we hypothesized that the results will eventually follow the Hardy-Weinberg expectations‚ which means the genotypes frequencies of the Drosophila melanogaster would remain constant; Therefore‚ no evolution had happened to the flies under the ideal conditions. After the chi-squared values were found in each week (table 1)‚ in the third generation where the chi-squared was found to

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
