Human Genetics            July 11th, 2017

Evaluate yourself for traits than are inherited through Mendelian Genetics

• Example: Detached or Attached Earlobes

Evaluate yourself for traits that are inherited through codominance or code for multiple alleles

• Example: Blood type

Evaluate yourself for traits that are inherited through polygenetics

• Example: Cephalic index (width of head)
