1: What is a gene?

( \newcommand{\kernel}{\mathrm{null}\,}\)

Learning Objectives

At the end of this chapter, you should be able to:

  • Appreciate the distinction between classical / transmission genetics and molecular genetics.
  • Define the following vocabulary from transmission genetics: allele, homozygous, heterozygous, genotype, phenotype, dominant, recessive, test cross
  • Propose a simple genetic model that is consistent with the result of a cross (with one or two traits with simple Mendelian inheritance.)
  • Predict the genotypic and phenotypic ratios of a cross, given a genetic model.
  • Apply the sum and product rules of probability to simple Mendelian crosses
  • Explain how the central dogma connects DNA sequence to a protein's amino acid sequence.
  • Predict the amino acid sequence that results from transcribing and translating a protein-coding gene.
  • Recall the various types of point mutations in a protein-coding gene and predict their impact on the protein’s amino acid sequence.
