What will Artemesia's kids look like?
completely irrelevant to anything functional, but I started wondering
what Artie's kid(s) will look like. It turns out that goat color genetics is pretty darn complicated. And since I only know what Artemesia, her mother, her father, and Monte look like, I'm stuck with guesses.
Eyes are the easy part.
So-called blue eyes (which really look almost white on Artemesia) are
dominant in goats. Artemesia is heterozygous in this trait and Monte is
either heterozygous or homozygous, so 75% to 100% of her kids will have
terms of coat color, there are two proteins that determine color (while
lack of either protein makes a white goat). Eumelanin can be black
(like Artemesia's primary color), chocolate, or red, and phaeomelanin
can be almost white, gold (like Artie's father and her mate), or all the
way up to a dark reddish-brown.
There are various pattern
possibilities that show where on the body the eumelanin and
phaeomelanin turn up. It's likely that both Artie's father and Monte are
heterozygous for Awt , which produces goats solid in the phaeomelanin color (gold in their case). In contrast, Artemesia and her mother have the At
phenotype, which produces orange on the belly and on parts of the legs
with a eumelanin-based color everywhere else. The recessive alleles
carried by Artemesia's father and mate, though, are unknown.
What does this mean for Artemesia and Monte's kids? Since Artemesia can't be carrying the more dominant Awt
(or she wouldn't be black), 50% of her kids will likely have her
pattern (or the pattern of her father's father or one of her mate's
parents). The other 50% will likely inherit Monte's solid, pale-gold
Finally, there's the
issue of true white, which can be found on Artemesia's "frosted" muzzle
and ears. This is a dominant trait, but I don't think Artemesia's mother
had this phenotype and I'm pretty sure Monte doesn't, so our goat is
heterozygous and will likely only pass the frosting on to 50% of her
So, that's my analysis
--- mostly blue eyes, half with pale-colored hair like Monte, the other
half with who-knows-what darker pattern, and half with white frosting.

If you're not confused yet, go read the article I linked to above and I
promise you will be 100% confused by the end. Then look at the photo
above of Artemesia and her cousins and figure most of her kids will
probably look at least a little bit like them. I guess that was the easy
answer to my question....
