I know that with each succession of joeys in a het line (such as leu) that the percentage of het goes down. I also know that the percentage means the possiblilty of them having the gene, and once they are proven they are known to be a 100% het. So my question is, why do some people refer to the joeys of a proven het parent as 66% hets, and some refer to them as 50% hets? And how does the progression of het percentage continue down the line?

Very good question. I would like to know the answer to that one too.

Joeys from two 100% het parents would be 66% hets, joeys from a 100% het paired with a non het would be 50% hets.

Sorry, missed half the question...

100% to 100% = 66%
100% to 66% = 50-66% (would become 66% if the 66% het parent proves out)
100% to 50% or lower = same as last one since one parent is a 100% het you'll be no lower than 50%

Recesive Color expressed x any Possible % Het or non recesive color = 100% Het offspring.

They're ^ right wink

With 2 100% leu het gliders you would get 66% leu het joeys unless the joey was bred and proved out.

With a 100% and a 50% leu het you'd get 50% leu het joeys.

The ONLY way joeys are automatically 100% leu het is if one parent is a leu. In order to be 100% het the recessive color has to be shown in the parent and it will be passed down to all offspring.

i have one 100% leu het female and a 66% leu het male.
they produced a leu joey last year.

all their joeys they have had since then are considered 66% leu hets, even though both mother and father have the leu gene in them.


i hope this is correct.

regards,
nancy in detroit

Yes so your 66% male would be considered 100% leu het because he proved out and had a leu baby with the 100% female. And correct all their het babies would be considered 66% leu hets until they would prove out smile

Why are the het percentages we use for advertizing different than what they actually are? For example, breeding a 66% het to a 66% het would produce 49.5 % het offspring, so why do we say 33% instead? I understand the the 66.5 being classified as 66, but why would a 49.5% het and a 36.13% het both be classified as a 33% het when there is a fairly significant difference in percentage?

Also, I know the chart clearly specifies what the percentages of offspring are, but I'd like to know why. For instance, why do two 100% hets produce 66% hets, but when you use the square it looks like 75% of the time the joeys will have the leu gene? What determines these percentages?

66% to 33% IMO, is because if the parents are 66%, then neither have proven, so you halve the % of the highest parent. If I had a 100% to 66% pairing, I'd say the joeys were 50% because I can't prove the 66% parent has the gene at all, and shouldn't factor into the equation. With both parents possible hets, it's better to guess low than high; better to be pleasantly surprised than have unrealistic expectations.

75% of the time, the joeys WILL have the gene, but one will be white. The 66% is from the "two of the three HET joeys should carry the gene". You wouldn't factor in the joey that displays the gene.

And remember, each of these coin tosses on who gets the gene, is for EACH joey, not an average. I've had a leu to a het throw nothing but white, and I've had a het pair (50%s proven out to 100%s) take 6 joeys to have white.

You would classify their joeys as 50 % leu het unless they prove out. That would show your female does carry the leu gene and is therefore also a 100 % leu het, and any gray joeys would be 66% leu het thumb

Your pairing will give you 50% leu het joeys unless the girl proves to carry the leu gene and you get a leu. They they will all be 66% leu hets and leus. smile
