I have several white (albino) turtles. How can I test whether their mutations are in the gene or not?

Solution

Answer:

The most simple test for detecting whether the mutations are in the same gene is complementation (cis/trans) test.

It more specifically determines if two recessive mutations producing the same phenotype are present in the same gene. The test is performed by crossing two individuals homozygous for different recessive mutations exhibiting the same phenotype.
