polymorphism

BoNE allowed the team to establish the cause of the Yorkshire syndrome -- and pinpoint a specific single nucleotide polymorphism that is protective.

"Our results support the intriguing possibility that numerous other traits that are sex-specific but more difficult to investigate are genetically encoded on the matrilinear genome like the color polymorphism of the female cuckoo."

The researchers found that the anemones' color variation, or polymorphism, is controlled by different versions of a single fluorescent protein gene.

However, there have not been decisive links between feather colour polymorphism and different environments until now.

The researchers found gene variants that link colour polymorphism and potential adaptations to cold environment.
