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

In arid conditions, RWC values of less than 50% cause most plants to die

whereas values closer to 100% indicate plants are less affected by drought stress.

Photoreactivation; Ultraviolet irradiation causes formation of thymine dimers. Upon exposure to light, DNA photolyase breaks the ring formed between the dimers to restore the two thymine residues.
