What is a pedigree?

A pedigree is a chart which shows the inheritance pattern of a given trait or characteristics for among members of a particular family.

A pedigree shows the line of descent or inheritance among family members.

Since the Tay-Sachs disease is a recessive trait, it is only inherited when the offspring are h0m0zygous for that trait.

The genotypes are represented as follows:

  • TT = normal
  • Tt = carrier
  • tt = disease

Therefore, the offspring that will have the Tay-Sachs disease are those with the genotype tt.
