Spider question

Wow. That was a lot of work. It is still fairly close to the 50/50 mark. That's interesting, thanks!

Very cool stats! You could make sure to collect the info on the stats of any clutches each year, and continue to check.

Just curious... what was the odds for the male spider - normal female clutchs overall, with ALL clutches figured in, instead of just the "matching clutches" for the way you did it? Since you had the odds percentage for the All clutches from female spiders, I'd like to know what the actual odds percentage was for the All clutchs from male spiders!

Kudos

It was almost 45% from total clutches produced by male spiders to normal females.

Hi,

While you were compiling all this did you happen to get info on spider to spider breedings with clutch sizes and morph ratios?

No I was only doing Spider to normal breedings. I know that there would be a huge jump in the amount of spiders produced from Spider to Spider which is why I only did the Spider to normal.

There is a similar assertion in horse breeding and dog breeding about certain colors and about breed traits. For instance, if you are breeding draft horses to light horses, you breed light mothers to maintain certain traits or light fathers to maintain certain other traits. That one is more vague than teh color traits though. I think that if you are breeding for splashy paints you want the mother to have the strong color for maximum gene expression. (I am going from memory of articles read. So my memory could be off.) tatt, have you got any data on that? Articles?

I have nothing about horses but I do know what you are talking about... Kinda...

Pity. :(

The size and make up of the clutches in those kind of numbers might have been an intresting indicator on the homozygous spider question.

dr del, you could do the same thing though. Call or email all the ball python breeders that mention breeding spiders, and ask if they bred spider to spider, and what was the results.
I'm sure most wouldn't mind giving you the information. It would be a cool little study to work up. Given the number of hobby breeders with at least one spider to breed, it could be a great deal of information.
I know! You should get a government grant for the study! LOL.

well im 21 years old and already balding, im sure it will be gone when im 30. every man on my moms side had hair til the day they died, however just about every man on my dads side has lost it. i think im walking proof that the whole balding thing being on your moms side is eigher not that simple or just bullcrap completly.

but i think it was said before, the spider gene is not the same as balding, its a simple dominate trait (well mayb not simple, we still don't seem to have a solid answer on whole "why are their no super spiders")
