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.

Very comfortable Slippers. Great buy!
Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal
I bought these to replace a pair of slippers that I have had for years that are very similar to the slippers I bought, but I had worn a hole in the leather on mine, so I had to find something new and similar. These slippers are worth the money they are very comfortable, and I am sure they will last for years. They are a little tight around the ankle cuff but they are still new and I am sure they will wear in a little more when I start wearing them more.

Great slippers but disappointing quality.
Size: 7.5-8.5 Women/6-7 Men, Color: Ash, Size: 7.5-8.5 Women/6-7 Men, Color: Ash
Extremely comfortable, attractive slippers but the stitching came loose on both leather trim areas almost immediately. I tried to sew/glue down the stitching (as seen in photo) but it kept unraveling. Disappointing as these slippers are great in every other way (though they do run a bit big...I wear a 9 but ended up with a 7.5-8.5 which fits with a bit of room to spare even with thick socks). I just hope they hold up after my latest attempt to stop the thread from pulling out any more as I do really love wearing them. Perhaps I just got a bum pair?

Very thin and comfortable. Wash well.
Very thin sock if that is what you are looking for. They stay up and wash well. There is a toe seam but you can position it out of the way

So comfy and just the right size
These are the cutest most versatile socks. The weave is just right, not too thick or thin. They don't fall or shift down your heel while walking in shoes. They launder exceptionally well. The height on the ankle is perfect for jeans, business casual pants or a quick change into gym clothes. I need more.
