Theory Pony genetic studying thread

[yisetab28 89]

So, as you may all know if you have been to high school, there are dominant and recessive genes. Let's take (only an example) a pony with a "rainbow hair" gene and another with a "blue hair" gene. If the rainbow hair gene is recessive and the foal made by the two ponies has one rainbow and one blue hair gene, the foal will likely have blue hair. How can we apply this to MLP? By examination of parents and foals in the show, we can create a map of dominant and recessive genes, and use it to find out some stuff we've been asking, stuff like if Dinky is really Ditzy/Derpy's daughter, finding out how Scootaloo's family was and many other parent-foal relationships. I was thinking we could all examine different families from MLP and draw out a map of dominant and recessive genes.

So, first analysis, Rarity's family. Rarity's mother is an unicorn who has a purple mane and pink skin, while her father is an earth pony who has a brown mane and white skin. Because the two daughters they had both have white skin, we could imply that the white skin gene is dominant, if this result is repeated in other families.. The problem is with the mane: Rarity's mane is fine, her purple mane probably coming from her mother, but how can Sweetie Belle have a mauve mane? It's because things are never that simple in studying living creatures. That's why I like "hard sciences" or however you call it in English more. You see, as we talked earlier about dominant and recessive genes, the dominant gene does not erase the recessive gene. Even is that rainbow hair gene was dominated by the blue hair gene, the gene is still here. What could we imply? That a mane with two shades of mauve is a recessive gene, but that Rarity's parents both had it and transmitted it to their daughters. This would mean that somewhere in Rarity's family, there could be another pony with a mauve hair gene, but that got that gene dominated by another color. This could also explain why both sisters are unicorns. Their mother obviously has the gene, but not their father. This could mean that either the unicorn gene is dominant, or that Rarity's father had an ancestor with the unicorn gene and transmitted it to his daughters. 

 

 

So, what are your findings about genes in the pony universe? post them here.

Rarity dad is also a unicorn as seen in one of the season 4 episodes, (can't remember which) but it did show this
