Edvotek® Chickcheck: The Genetics Behind Blue Chicken Eggs

Explore the genetics of chicken egg color using hands-on PCR.

• Detect a viral DNA insertion near the SLCO1B3 gene that causes blue eggs
• Compare PCR band patterns to identify egg-color phenotypes
• Use genetic results to select breeding pairs for homozygous blue egg-laying chickens

In this experiment, students will investigate the genetic basis of chicken egg color by using PCR to detect a viral insertion near the SLCO1B3 gene, which is responsible for the blue egg color. The PCR products are analyzed using electrophoresis to determine phenotypes and select breeding pairs that will produce homozygous blue egg-laying chickens.
