Grey Cats – Breeds, Genes and Inheritance

All about grey cats

Also referred to as blue or Maltese, grey is a common coat colour in both purebred and domestic cats. Grey is the dilute form of black, caused by the aptly named dilution gene which is caused by a single base deletion 1 bp in the melanophilin (MLPH) gene. This gene provides instructions for making melanophilin, a carrier protein that is found in pigment-producing melanocytes. Melanophilin is essential for the even distribution, transport, and translocation of melanin (pigment granules). Menalocytes are specialised cells that contain organelles known as melanosomes. Melanosomes synthesise, store and transport melanin out of the cell via the dendrites to neighbouring keratinocytes (keratin producing cells).

Recessive Genes in Cats

Recessive genes in cats

What are genes?

A gene is a segment of DNA (deoxyribonucleic acid) that codes specific processes in the cat’s body by encoding proteins. These codes are the blueprint for the cat’s body and can encode proteins to build structures in the body (heart, eyes, bones etc), or provide directions for different processes, bodily functions and influence the cat’s physical appearance (hair and eye colour, coat length, ear shape etc).
