Holland Lop fur coat genes (the basics).

Holland Lop fur coat genes.

A_B_C_D_E_

A_B_C_D_E_ (the underscores mean it's the same gene after the letter, such as A_ is the same as AA) are the most dominant genes for Holland Lop fur coats, any recessive genes will be lowercase and or have letters after them such as aa would be recessive and at is recessive. There are also recessive genes that are more recessive than others such as aa is more recessive than at.

If Parent 1 has the AA gene and parent 2 has the aa gene; 100% of offspring would be Aa (Agouti but carry the recessive self gene).

A punnett square with the two gene sets "AA" and "aa".

If Parent 1 has the Aa gene and parent 2 has the Aa gene; 50% of offspring would be Aa (Agouti but carry the recessive self gene), 25% would be AA (fully Agouti), and 25% would be aa (fully self).

So that is the some of the basics of the punnett square and now I'll get into some of the basics of each gene set, soon I'll put out a post on each gene set.

A list of the genes. P.s. I order the genes in each gene set from most dominant to least dominant.

Gene set A_

The A_ Is the Agouti gene (dominant). The at is the tan gene. The aa is the self gene.

Gene set B_

The B_ gene (dominant) makes the base color black. The bb gene (recessive) makes the base color chocolate (brown). When the bunny has Bb it is black because black is dominant but carries a brown gene.

Gene set C_

The C_ gene set is color amount. C_ is the full color gene, cchd is the chinchilla gene, cchl is the sable gene, ch is the Himalayan gene, and cc is the albino gene.

Gene set D_

The D_ gene set is either dense or dilute. Dense keeps a solid color such as black, black but the dilute makes it blue colored. The dense gene is D_ and the dilute gene is dd.

Gene set E_

The E_ gene set stands for extension, this one's a bit complicated so I'm not going to go into it much but it is how far the color on the fur extends to the root. The genes include... Ed which is the dominant black gene, Es is the steel gene, E is the normal extension gene, ej is the harlequin or tri colored gene but is formally the Japanese bridling, ee is the non-extension gene.

Well I hope you learned some about rabbit genetics, you won't be able to write out any gene set's yet but now I hope you have a good grounding in the basics of gene sets for Holland lops fur coats!

The B_ gene set.

Gene set B_  The B_ gene set controls weather the base color is brown or black. The Black gene.  The black gene (B_). The black gene means black is the base color of the bunny's fur coat, that means that any color that is black changed black like blue (looks dark grey colored) has the base black colored gene. Variations of this gene: B_ & Bb. The Brown gene.   The brown gene (bb). The brown gene means chocolate is the base color of the bunny's fur coat, that means that any color that is chocolate or lighter or somewhat changed brown colored such as orange has the base chocolate (brown) colored gene. The only variation of this gene to show is bb. Here's some punnet squares for the variations these genes could have as out comes.  Here is if parent 1 with BB genes had offspring with parent 2 who had bb genes, all offspring would be Bb (black colored and carry the recessive b gene).   Here is if parent 1 with Bb genes had offspring with parent 2 who had Bb ...

The C_ gene set.

-
Gene set C_ The C_ gene set is one of the most complex gene sets of the five, it's called the color gene and basically controls how much pigment your bunny has in its fur.  Note: As in other posts I'll order the genes from the most dominant genes to the most recessive genes.  The full color gene (C_). This gene is pretty simple (it is the name) it's just the full color pigment in your rabbit's fur.  Variations of this gene includes: C cchd, Ccchl, Cch, & Cc. The Chinchilla dark gene ( cchd).  This gene shares dominance with the chinchilla light gene (cchl) or co-dominance. This gene shows the Agouti pattern but lightens any yellow or off white to white as well as doesn't let all the color pigment but most show, it also some times makes rabbits with blue eyes.  Variations of this gene includes: cchd, cchdcchl, cchdch, & cchdcc. The C hinchilla light gene (cchl).  This gene will not let the Agouti gene show and will let most of the darker pigment ...
