The alternate ky variant of the CBD103 gene disrupts the normal function of the CBD103 gene allowing
for agouti (A locus) gene expression and the inhibition of black pigment synthesis.
Studies monitoring their caches suggest that it doesn't take long
for an agouti to come and collect.
Not exact matches
Jirtle is well known
for his work on mice that carry the
agouti gene, which is highly vulnerable to environmental influences.
By robbing each other and hiding their loot,
agoutis took seeds farther and farther away from their starting point, each time replanting the seed in a new but equally nutrient - rich spot
for tree growth, the researchers report online today in the Proceedings of the National Academy of Sciences.
In these species, the gene
agouti controls the relative amount of red and yellow pigments in the skin, and melanocortin 1 receptor (Mc1r) does the same
for black and brown.
Although an
agouti can not devour large tropical fruits the way an ancient mammoth might have, it consumes the seeds, collecting and burying some to store as snacks
for later.
The research group studied
agouti caching on a Panamanian island, Barro Colorado, where they marked 16
agoutis for individual identification and set up video cameras to monitor activity at cache sites.
For example, one seed tracked was cached by
agoutis more than 30 times, journeying 280 meters from its starting point and more than 750 meters total.
Genetic testing of the CBD103 gene
for the KB variant will determine whether a dog is a genetic Carrier of
agouti gene expression.
This dog carries two copies of ky which allows
for the expression of the
agouti gene (A locus) which can result in a variety of coat colors including sable / fawn, tricolor, tan points, black or brown.
This dog carries two copies of KB which prevents expression of the
agouti gene (A locus) and allows
for solid eumelanin (black pigment) production in pigmented areas of the dog.
This holds true
for both solid colored and
agouti - patterned animals.
By 2020 we would like to have completed blood type testing, as well as just
for fun testing on coat length,
agouti, albinosim (colourpointing), coat colour, and with white markings.
Geneticists have not always agreed on what letters to use, but I like the abbreviations or symbols used by Dr. Clarence Little,
for the most part, and you can use your own words: «A» might refer to «
Agouti» or «All - over» pattern.
Keep your eyes sharp, looking
for lizards and small mammals (coatis,
agoutis, peccaries) on the ground, and once you get to the tree tops, try and spy colorful toucans and parrots.
