Description

E-LokusDer Melanocortin 1 Rezeptor (MC1R) auf dem E Lokus ist verantwortlich fr die Regulierung der Pigmentproduktion in Melanozyten. Eine Mutation im MC1R Gen fhrt zu einem nicht funktionalen Rezeptor und schaltet die Pigmentproduktion auf Pheomelanin um. Da die Produktion von Eumelanin deaktiviert ist, ist die Wirkung anderer Loci nicht mglich. Die Mutation ist rezessiv, daher sind zwei solche Allele notwendig, um die gelb rote (Pheomelanin) Fellfarbe

Der Melanocortin-1-Rezeptor (MC1R) auf dem E-Lokus ist verantwortlich für die Regulierung der Pigmentproduktion in Melanozyten. Eine Mutation im MC1R-Gen führt zu einem nicht funktionalen Rezeptor und schaltet die Pigmentproduktion auf Pheomelanin um. Da die Produktion von Eumelanin deaktiviert ist, ist die Wirkung anderer Loci nicht möglich. Die Mutation ist rezessiv, daher sind zwei solche Allele notwendig, um die gelb-rote (Pheomelanin) Fellfarbe auszudrücken. Verschiedene Hunderassen mit dem Genotyp e/e zeigen unterschiedliche Farbtöne von hellem Creme (Golden Retriever) bis tiefrot (Irish Setter). Der E-Lokus beeinflusst nicht die Pigmentproduktion an Pfoten, Nase und Augen (reguliert durch den B-Locus).

Das dominante normale E-Allel ermöglicht die Produktion von Eumelanin, daher werden alle homozygoten (E/E) und heterozygoten (E/e) Hunde entweder schwarz oder eine andere Farbe sein, wenn andere Loci exprimiert werden (B-, A- und K-Lokus).

Genotyp

Beschreibung

E/E:

Hund ist homozygot für das normale Allel; normale Eumelaninproduktion, die Expression anderer Loci kann die Fellfarbe bestimmen.

E/e:

Hund ist heterozygot; da das E-Allel dominant ist, ist die Eumelaninproduktion normal und die Expression anderer Loci kann die Fellfarbe bestimmen; Hund ist Träger der rezessiven Mutation und wird sie an 50% seiner Nachkommen weitergeben.

e/e:

Hund ist homozygot für das e-Allel; es wird nur Pheomelanin produziert; Hund zeigt eine Fellfarbe von hellem Creme bis dunkelrot.

Must have for a young puppy
Size: Small (Pack of 1), Color: Blue
Very helpful for our young puppy. Cleaning it isn't the easiest, but cleaning advice is easily found online and it's worth the hassle to have a durable lasting toy around

Perfect for small senior dogs!
Size: Extra Small (Pack of 1), Color: Pink
So I actually bought this for my senior Bolonka. She has a neurological disorder that does not allow her to have hard bones or treats, plus I am trying to protect her teeth for as long as I can. This is a GREAT toy. I like to fill up the middle with yogurt or peanut butter and things she can lick instead of bite into. This is the PERFECT size for her. She likes to play with it even without a treat on the inside. She just carries it around the house , as its not heavy at all, and throws it around, it is too cute! It is not loud at all, the only noise that comes out is if shes got a ton of saliva and her teeth rub against it. I just pulled it off the packaging, washed it, and it was ready to go. It will last forever with my baby because she doesn't chew hard so I am unsure about the durability for bigger pups or dogs who are heavy chewers. I am so glad I got this for her and I would HIGHLY recommend it!

Good product misleading size.
Size: Small (Pack of 1), Color: Blue
Really disappointed about the size. It is way too small for my berniedoodle. He still likes it for play but I’m afraid he might swallow it. It’s very sturdy tho and is chew resistant. I guess I didn’t pay attention to the size. Looked big in the picture.
