Tested Pony: Lainey

Lainey is a 2025 filly by Don Leonard Stud II and out of Milly Sue. Both of her parents are still on Assateague and she's a full sister to 2024 buyback Jan's Little Piece of Heaven. Lainey looks quite a bit like her full sister. Since Lainey is now in Etalon's database we'll be able to parent verify other foals of her parents and the future foals of her sister. Thanks to her owner Brianne for testing her and sharing the results!
Lainey's color test results: A/a, e/e, nd1/nd1, SW1/n, TO/n, W20/n

Lainey is a chestnut, e/e. She carries an unseen copy of the bay causing agouti, A/a. Since she doesn't have black agouti down't have anything to do so can only be found via testing. There's quite a lot of evidence that her sire Don Leonard Stud II has two copies of agouti. He's never sired a black foal, even out of black mares like Milly Sue. His tested foals like Lainey have had agouti.

She has two copies of nd1 which can cause primitive markings like dorsal stripes.

Lainey is heterozygous for tobiano or TO/n. Only her sire is a tobiano so only he could pass it on to her.

Lainey has quite a lot of white and a partial blue eye which indicates she has more white patterns than only tobiano. Her dam is a Riptide daughter so I wasn't too surprised to see she has one copy of Splashed White 1. She also has White 20! Lainey's the 2nd Chincoteague to test as having W20. The first was a Riptide daughter, perhaps it comes from him. Something to think about!
