Question: Genetics in Practice - make sure you know the answers to the questions I asked in the chapter PowerPoint.
Terms from chapter to review (in addition to those directly mentioned in specific topics below): evolution, gene pool, genotypic frequency, allelic frequency, pre-zygotic, post-zygotic, speciation
Calculate genotypic and allelic frequencies for an autosomal locus with two alleles given population information (total number of individuals and number of individuals with each phenotype).
Describe the Hardy-Weinberg law (i.e. equations) and the conditions required for genetic equilibrium to exist in a population.
Apply the predictions of the Hardy-Weinberg law to calculate genotypic and allelic frequencies for populations in HW equilibrium given one piece of information (such as q2)
Describe the forces that drive evolution (genetic drift, nonrandom mating, mutation, migration, and natural selection) and their effects on allelic frequencies of a population.
For genetic drift, also explain the causes of genetic drift (sampling error, randomness), what factors influence the magnitude of drift and what bottleneck effect and founder effect are.
For natural selection, explain how evolutionary change of this type differs from the others
Identify which forces increase diversity and which decrease diversity WITHIN a population
Identify which forces increase diversity and which decrease diversity BETWEEN SEPARATE populations
Recite the biological species definition and describe its limitations. Get online assignment help – 100% Original & AI-Free Content.
Be ready to define Reproductive Isolating Mechanism (RIM) and describe at least two examples.
Explain the difference between allopatric and sympatric speciation
Identify the forces that drive evolution in each type of speciation.
Explain how phylogenetic trees are used to show evolutionary relationships and the difference between anagenesis and cladogenesis in evolutionary relationships and appearance on the tree.
Explain why rates of nucleotide substitutions vary among different parts of the genome and within a gene.
Define the molecular clock, including the key assumption it makes and how scientists apply it to evolutionary studies.
