How to further spotting?

[Crystal]

My apologies if I have asked this before [Many years ago!]
But I cannot remember, how does spotting exactly work?
I am referring to producing potential offspring with more white. Not extremely but Mottled gerbils are truly stunning to me. So what exactly does it take to even begin such a goal? I'm not aiming for it just yet but am curious

I did produce a pup with the most spotting I've ever had in 2010;

She came from a Pied Black mother and a Sp. Nutmeg. (& the mother came from Sp. Agouti+Honey Cream)

I have noticed that self bellied parents are more likely to have more heavier spotted pups but why and how?
I currently have two spotted male and female; the Sp. Male Siamese being that black pup's grandson and the female is a Sp. Black.
Will their someday-pups have more white than them or same?
-Thanks in advance!

If you want more white, you need to use parents with more white. In both spotting patterns and bibs/knuckle-dusters. If you only have access to low-white spotted gerbils, pair them with non-spotted self-bellied gerbils with lots of white on the chin and paws.

I like your interesting comment about the self bellied adults having more spotted pups, as I hadn't really taken that into account in my spotting. All I knew was my spotting was generally most extensive on Blacks - with 3 out of my four most pied pups being black and the other was Agouti.

My spotting all started with an Agouti PEW who I didn't know was spotted and we got a few nice collared pups, but I bred the nicest character pup (with virtually no visible spotting) to a Nutmeg from non-spotted parents for several generations and I got many spots and some pied with blazes.



However, having kept the black male (above) and mating him to a Saffron (with white feet), and then a black female - nothing like it - just tri-spots and mis-shapen collars. Mind you I have only had very few matings to compare.

Hmm? Perhaps I needs to keep trying...

Thanks for the replies! Since The last hm, 5 breeding pairs I've bred, they all were either both spotted or one was spotted and the other was a white bellied so I have not bred a solid-non-spotted in ages 0_0; Though I get an understanding now.

Also Betty, to me the A/White bellied pups I've produced that were spotted usually had what you got.
Broken collars or half blazes, but of the past 5 years I had two Agouti-based pups who were the most heavily spotted and were a surprise to me.
Like Shooting Star said, now I understand why my first LCP Agouti had spotting on his back; His father was a male with high white markings (non-spotted black). As for my second Agouti, she came from a normal Sp. Golden Agouti father and a Red eyed honey mother, so when it comes to white bellies and spotting it's more random to me.
