Fat Tail Genetics

[Duncan]

Can anyone tell me what the genetics are for the stripe vs. non-strip in fat tail geckos? I have a striped male and both a striped and non-striped female. I was sure that my first two clutches of eggs this year were from the striped female, and so far they have come out 3 striped: 1 non-striped. This would work out to be a perfect Mendelian ratio if both the parents were het for stripe and the striping was the dominant trait; but for some reason I thought the striping was a recessive trait. I guess not?!
Anyone with any experience in fat tail genetics want to confirm that it is a dom trait?
Thanks,
Duncan
