Chapter 4 Summary

The topics covered in this chapter can be summarized as follows:

  • Pedigree analysis can be used to determine the mode of inheritance of specific traits such as diseases.
  • Loci can be X- or Y-linked or autosomal in location and alleles either dominant or recessive with respect to wild type.
  • If the mode of inheritance is known, a pedigree can be used to calculate the probability of inheritance of a particular genotype by an individual.

Take a look at the video below, Pedigree Analysis, by Nicole Lantz (2016) on YouTube, which summarizes the various pedigree patters observed based on the different modes of inheritance.
