# How Do Appaloosa Genes Work Together

<p class="callout info">*Appaloosa Spotting Genes are some of the most complex Genetics in Hunt&amp;Jump, they work together and react to one another in such a way, that every horse is unique.* </p>

#### **Proposed Talking Points**

1. In Game Vocabulary
2. How Do Appaloosa Genes Work Together

##### **In Game Vocabulary**

<details id="bkmrk-in-game-vocabulary-a"><summary>In Game Vocabulary</summary>

**Allele**: It is a variant, or mutation, to a gene (e.g., LPP1 and LPP2 are Alleles of the LP Promoter Gene). Rarely used in H&amp;J language, but seen in this article.

**Appaloosa Characteristics**: Appaloosa (LP) will add mottling to the horses skin as well as *Varnishing*.

**Gene**: A section of DNA that codes for a specific inheritance (e.g., Appaloosa is the Gene). For the purpose of H&amp;J, Alleles are called Genes. Genes are what give our horses a variety of colors and patterns.

**Heterozygous**: One copy of an Allele (i.e., LP/-). [See this section for more information](https://wiki.huntandjump.com/books/genetics-101/page/how-to-read-genetic-testing-results-a-complete-guide-to-understanding-your-horses-color).

**Homozygous**: Two copies of the same Allele (i.e., LP/LP). [See this section for more information](https://wiki.huntandjump.com/books/genetics-101/page/how-to-read-genetic-testing-results-a-complete-guide-to-understanding-your-horses-color).

</details>##### **How Do Appaloosa Genes Work Together**

**Heterozygous Appaloosa (LP) vs. Homozygous Appaloosa (LP/LP)** By itself, the LP gene is just a switch to turn on the expression of other genes. It will add Appaloosa Characteristics, but those characteristics do not change between Heterozygous and Homozygous expression. However when the LP gene is Homozygous, and paired with other Appaloosa Spotting Genes, you will see an extreme difference from the Heterozygous expression.
