Motley/Stripe Question?

Hi Everyone,
I know that Motley and Stripe are alleles that fall at the same loci and Motley is dominant to Stripe. Meaning, if I breed a Motley to a Stripe the whole clutch should be in fact Motley het Stripe as well as true genetic MotleyxStripe. I know that when you breed a Motley het Stripe x Motley het Stripe that the clutch should consist of Motley and Stripe. My question/s is this. Would the Motley that were produced by pairing a Motley het Stripe x Motley het Stripe also be 100% het Stripe as well? Or would only 2/3 of them truly be het Stripe because both parents are het Stripe? Do my questions make sense? I hope so. :shrugs:

Jay :cool:
 
I'm a little too braindead today to work ratios, but there would be some Motleys that were not het Stripe in the bunch. 2/3 being het Stripe would sound about right....
 
There will be 1/4 homo motley (because chance = 0.5 x 0.5), 1/4 homo striped((chance = 0.5 x 0.5) and 1/2 motley het striped (1/4 'motley from dad + striped from mom' + 1/4 'striped from dad + motley from mom')
 
Blutengel pretty much covered it

The easy way I get it in my head is if you FOIL ms x ms you get:

mm, ms, ms, ss.

So 1/4 would be motley NOT het stripe
1/2 would be motley het stripe
and 1/4 would be stripe NOT het motley

So yes, 2/3 of the motley's would be het stripe, and 1/3 would not (theoretically)
 
Ah, I just understood the OP's real question LOL I was thinking: where does the 2/3 idea come from? I get it....
 
Thank you all very much for your replies. I thought I might be right but I wanted to positively make sure. Thanks :cheers:

Jay :cool:
 
I may not have much morph experience, but I do know my math pretty well (when I don't get myself confused that is :) )

From what I see, yes of the motleys 2/3 of them would be het stripe. I straightened it out in my head by looking at the percentages instead of the fractions.

75 of every 100 hatchlings are motley. 50 of every 100 hatchlings are motley het stripe. 50 of those 75 motleys are het stripe, which is also 2/3 or 66%. I have a bad tendency to make silly mistakes though so let me know if that is off.
 
Motley and Stripe revisited

I know this has been talked about before but I still need clarification to properly ID my babies.

I bred a motley butter male to a motley sunglow female (what they were sold as). My outcome should have been all amel motleys (het hypo het caramel). However in my clutch of 9, I got one full stripe and 3 with partial stripes, the rest are all ‘normal’ looking motley. Here are a few (bad) pics fresh from the eggs…

I read on this website http://iansvivarium.com/viewtopic.php?f=21&t=2619 that breeding het motley het stripes would give you 75 % motley 66% poss het stripe and 25% striped which seems to be the same ratios you guys are giving here and kind of falls in line with what I got (still a couple eggs that may pip).

I personally just wanted motleys without the stripe in the mix.

Take a look at the parents, so this sunglow motley is actually a motley/stripe? She does have a couple connected saddles but I thought that was just normal variation.

The motley dad doesn’t display any striping but would the outcome of the babies mean he is also het stripe or is it possible the stripey-ness is only coming from the mom’s side? (I assume he would have to be het stripe to get striped babies?) (this is an old pic, he's bigger and more yellow now)

I was planning next season to breed this same butter motley to a normal het snow motley (completely unrelated, no striping in her genes going back 2 generations). Does this mean I might get stripes again? Or would those babies be poss het stripes from the dad’s side?

Thanks for any options, let me know if you have any questions to clarify what I am trying to ask.

Well that is great news because I didn't want to deal with the stripe genes! I can see in the photo you linked also how the striping is different on the stripe gene animal compared to the striped motley. Glad to know it's just part of the normal variation of the motley gene. Now to decide which do I want to keep.. the stripers or the 'classic' motleys.. hmmm

Pin-striped motleys tend to be slightly higher priced as they are less common and many find them more desirable, but in the end, it is your personal preference as to what you want to keep and breed.
