#Unit 8. Inheritance Biology

Autosomal Recessive Traits

Autosomal recessive traits normally appear with equal frequency in both sexes.

The trait seems to skip generations.

When both parents are heterozygous, approximately one-fourth of the offspring are expected to express the trait.

Recessive traits appear more frequently among the offspring of consanguineous matings.

Example - Tay–Sachs disease, sickle cell anemia, cystic fibrosis, PKU
