Have two Lavendar males and plan on keeping at least one chocolate hen and a royal purple/pearl hen and possibly a white. Any idea what color keets I can expect?

I guess it depends on whether any of your birds are split or heterozygous for the same color. For example, if your lavender cock had no hidden genes and paired with a royal purple hen that had no hidden lavender gene, then the keets would be expected to be Pearl grey. However, if that RP had one recessive lavender gene, then you’d get 50% lavender keets. Your white hen though would be expected to produce pied keets if she pairs with a solid colored cock.

The group that you think are great with the color genes are making up their own names for the color genes instead of using the accepted names. There is no lavender gene. the color gene for Lavenders is the same blue gene that Coral Blues have. The difference between a Lavender and a Coral Blue is that a Lavender has at least one full dotting gene and a Coral Blue does not have a full dotting gene but does have at least one semi-dotting gene.

I have not seen any proof of what color genes a Royal Purple does or does not have. The only thing I know for sure about Royal Purples is that they do not have a full dotting gene and have at least one semi-dotting gene.

The hidden possibilities for a mating between a Lavender and a Royal Purple can be much more complex than what you describe. I have never gotten any Pearl Gray offspring from my Royal Purple. That leads me to believe that my Royal Purple does not have a gray gene.

For whatever it's worth, Bella (I have to say "flawed buff dundotte" d/t seeing so many pix of same tagged BD ,you say brown)
Came from BD male mated w/either Pied gray. or Pied lavender.
She mated w/semi dotted RP Blue and fully pearled lavender Nugget (their parentage unknown).
All keets were PG

For all of the keets to be Pearl Gray, the Lavender had to be the father of all of them because it was the only one that had the full dotting gene. For all of them to come out Pearl Gray, your Nugget had to be homozygous for the full dotting gene.

All of those keets have to be heterozygous for the full dotting gene and the recessive blue gene.

I myself am pretty randomly breeding whatever colors I get from whichever birds pair up. However, the nomenclature I’m using is from groups that are currently breeding for newer guinea fowl colors, so they are the ones who seem to be able to get workable results from their genetics system. There have been published results of tests breedings in guinea fowl that support royal purple as being the result of being homozygous for the margarogene factor (m, semi-pearling)

https://academic.oup.com/jhered/article-pdf/87/2/138/6452301/87-2-138.pdf

This same paper also discusses the lavender or blue gene (i) as being recessive to wild type (I, pearl grey), with a lavender bird being homozygous for i/i in order to express the lavender color. And, I think that this paper agrees with you, that a Coral blue bird would have the i/i genotype as well as the m/m genotype.

What color birds do you think that ericwaddles flock would produce?

Bella was fully dotted..dundotte is fully pearled version of buff. Even if we go with her being brown, they're fully dotted. Not debating you, just trying to keep up.

Okay, I missed that part.

Lo...not that I'm at all shocked to hear Nugget trumped poor Blue's thunder. Such a brat.

Royal Purples can be homozygous for semi-dotting. They do not have to be homozygous. They can be heterozygous for the semi-dotting gene as long as the other gene is for the no dotting gene. I know for a fact that my Royal Purple is heterozygous for the semi-dotting gene and the no dotting gene. When paired with a homozygous no dotting gene Powder Blue, she would produce no dotting Violets. This year when paired with a Coral Blue male that is heterozygous for the semi-dotting gene and the no dotting gene she also produced a Violet.

Full dominant genes like the full dotting gene do not have to be homozygous for the condition to be expressed. The semi-dotting gene is a partial dominant gene as it is recessive to the full dotting gene but dominant to the no dotting gene. As long as the full dotting gene is not present, it only requires one semi-dotting gene for the condition to be expressed.

The only one that has to be homozygous is the no dotting gene for the condition to be expressed. It is recessive to both the full dotting gene and the semi-dotting gene.

I don't know if there is actually a no dotting gene or if it is a case of the lack of both the full dotting gene and the semi-dotting gene. Either way it is convenient to refer to it as the no dotting gene.
