• Meiosis: two divisions, and why no two gametes come out the same
  The two divisions of meiosis, homologous pairing and bivalents, crossing over at chiasmata, independent assortment and the 2 to the power n…
• Monohybrid inheritance: genetic diagrams that score
  Genotype and phenotype, dominant and recessive alleles, the five-line layout of a genetic diagram, monohybrid ratios, test crosses, codominance…
• Two genes at once: 9 : 3 : 3 : 1, the ways it breaks, and the chi-squared test
  Dihybrid crosses and the 9 to 3 to 3 to 1 ratio, the dihybrid test cross, autosomal linkage and recombination frequency, epistasis with the 9:3:4…
• Hardy-Weinberg: what alleles do in a population when nothing acts on them
  Gene pools and allele frequencies, the Hardy-Weinberg principle and its five conditions, the equations p plus q equals one and p squared plus two pq…
