Discussion Ideas - Chapter 19
The nonchemical approach to medical genetics is largely
based on the concept of dominant and recessive genes. This chapter
presents human genetics from this perspective, along with exceptions,
such as incomplete dominance, polygenic inheritance, and multiple
alleles. Sex-linked inheritance is also a special case because
females are XX, but males are XY.
Relevant research into genetic disorders is an important
part of this chapter, and its up-to-date coverage should help
students understand the latest breakthroughs, which are reported
almost daily. The Health Focus outlines how genetic counseling
can be used.
