General Biology 212 Laboratory Session Three

1
General Biology 212 Laboratory Session Three

• Evolution at the Genetic Level
• (Hardy-Weinberg Expectations)

2
Purpose

• To lay a foundation for an understanding of
  evolution as a process of genetic change
• To fulfill this purpose you will,
• Develop a predictive model of allelic
  distribution at the population level by applying
  principles of Mendelian inheritance
• Use the predictive model to predict genotypic
  distribution

3
Materials and Methods

• Lab manual and calculator
• Read and work through the laboratory experiments
  designated as Components I through VII

4
Important Terms and Concepts to Understand

• Diploid zygote
• Dominant and recessive alleles
• Genotype and phenotype
• Autosomal loci
• Monohybrid and dihybrid crosses
• Population distribution of alleles
• Hardy-Weinberg equilibrium

5
Formula to Know

• Calculation of Allele Frequency
• Laboratory manual, pg. 33
