  • Hardy Weinberg Problemset

    Hardy Weinberg Problemset

    Students can practice using the Hardy Weinberg equilibrium equation to determine the allele frequencies in a population. This set of 10 questions gives students just enough information to solve for p (dominant allele frequency) and q (recessive allele frequency). They will also calculate the percentage of heterozygous individuals (2pq). I designed this worksheet for an…

  • Investigation:  What Factors Affect Cricket Chirps?

    Investigation: What Factors Affect Cricket Chirps?

    One of my favorite scientific method activities was a project that used a flash simulation to investigate cricket chirps and how the frequency is affected by temperature, humidity and wind speed. ¬†Unfortunately, flash is no longer supported by modern browsers. ¬† This alternative assignment asks students to listen (and count) cricket chirps, create a data…

    What is a Map Unit Anyway?

    Chromosome maps illustrate how far alleles are on a chromosome using a MAP UNIT. Map units are based on the frequency of cross-over
