Dear Baby Ribbon:

Why did baby twinkle-eyed ponies not have twinking eyes?

Dear Featherfire,

Because nearly every physical human trait is indeed produced from some genotype, many people are confused by topics like this.  It may be oversimplified, and I'm no geneticist, but I do happen to know everything, as you know.  I suggest you think of it this way:  The only thing ponies inherit from their parents is their gender and their basic pony type (pony, unicorn, pegasus, flutter, sea pony, etc.).  

Everything else is a unique product of their own distinctive pony magic.  That is how the Sparkle Ponies got their sparkles, the scented ponies got their scent, the Brush & Grow Ponies got their mega-hair, the Twice As Fancy Ponies and the Merry-Go-Round Ponies got their extra decoration, and so forth.  Even body color, hair color, and symbols are not necessarily those of our mothers (see topic on Pony Names).

Perhaps my explanation is oversimplified, though.  I got out my genetics book from when I was in kindergarten (Genetics! No kidding!  I remember it was in between Tying Your Shoes and Finger Painting.  Finger Painting was actually harder, for obvious reasons) and started reviewing.  Actually, there are certain traits that are not directly inherited, but are more likely to occur in children if they occured in parents because of the rules of Pony Magic.  Examples of these traits are rainbow hair, so-soft fur, twinkle eyes, and twice as fancy symbols.

To throw another wrench into the matter, some Pony Magic takes awhile to develop, like twinkle eyes, so-soft fur, scentedness, or even hair color.  For example, my mom is a So-Soft pony, and I don't have fur.  That means either I will never have fur, or I may eventually grow fur someday.  

I hope not.  I really like bubble gum.  I wonder if they make pony Epiladies . . .

So, why do baby twinkle-eyed ponies not have twinkle eyes?  Only time will tell!
