Chapter 6: Gene interaction

In this chapter, you will learn how to:

  1. design experiments to test two or more mutations for allelism, using progeny ratios or using complementation tests.
  2. infer various types of dominance based on the phenotypes of heterozygotes.
  3. recognize the diagnostics for the presence of a lethal allele.
  4. infer interaction of different genes, based on modified Mendelian ratios.
  5. formulate reasonable molecular hypotheses to explain various types of gene interaction.
  6. recognize the diagnostics for variations in penetrance and expressivity of genotypes.
  7. predict progeny of crosses in which genes show one or more of the above types of interaction.

Chapter 7: DNA structure and replication

In this chapter, you will learn how to:

  1. assess the types of evidence (historical and modern) that can be used to show that DNA is the genetic material.
  2. evaluate the data used to build the double-helix model of DNA and explain why it suggests a particular mechanism of DNA replication.
  3. illustrate the features of DNA replication that contribute to its speed and accuracy.
  4. explain why chromosome ends require special replication and the consequences to human health if end replication is defective.
