Parblue? Turquoise? - Agapornis

... By this time it was clear we are dealing with an allele of the blue gene. In other words, it was clear that this was a ‘parblue’ mutation. A new name was needed but ‘whiteface’ wasn’t exactly suitable, considering in fischeri and personatus neither have a white face. ‘Yellowface’ wasn’t suitable ei ...

... Each parent donates one set of instructions, known as genes to the offspring. The Zygote (fertilized egg) would have at two least genes for each characteristic (one from mom and one from dad). The two genes that govern the same characteristic are known as alleles. A punnett square is used to visual ...

New Mutations in the KVLQT1 Potassium Channel That Cause Long

... Background—Long-QT syndrome (LQTS) is an inherited cardiac arrhythmia that causes sudden death in young, otherwise healthy people. Four genes for LQTS have been mapped to chromosome 11p15.5 (LQT1), 7q35–36 (LQT2), 3p21–24 (LQT3), and 4q25–27 (LQT4). Genes responsible for LQT1, LQT2, and LQT3 have be ...

The reason for this is that if a specific order is required then there are no other possible combinations maki ...

Epistasis



Epistasis is a phenomenon that consists of the effect of one gene being dependent on the presence of one or more 'modifier genes' (genetic background). Similarly, epistatic mutations have different effects in combination than individually. It was originally a concept from genetics but is now used in biochemistry, population genetics, computational biology and evolutionary biology. It arises due to interactions, either between genes, or within them leading to non-additive effects. Epistasis has a large influence on the shape of evolutionary landscapes which leads to profound consequences for evolution and evolvability of traits.
