Genetically speaking?

[jcaustralia]

ok i have a question on genetics. i will use spiders & albino's as my example.

ok i purchase a 100% het for albino male and breed it into a female spider. will the babies be 100% het for albino normal/spider, or will it "wash out" the albino gene and make it lets say 66% het for albino?

i hope i asked this right???? please learn me somthing?

100% het albino to a spider........Each egg has a 50/50 chance of hatching out as a spider or a normal looking baby...and each one that hatches will be 50% het for albino...meaning they have a 50/50 chance of carrying the albino gene.

[jcaustralia]

ok i understand there is a 50% chance of the gene being passed on, i am wondering i guess on the gene percentage itself, say hypothetically you know one of the babies has the albino gene, what would be the % of that gene?, so what would be the chance of throwing an albino baby when raised and bred back to the 100% het albino parent?

i may not be asking it right?

You need to prove out your 50% hets. out of 4 poss. hets 2 will be normals and 2 will be 100% hets., you need to breed everyone to find out which ones are het.

The answer JLC gave should be enough.... but I'll try to simplify things...

100% Het Albino to Spider will give you (In 6 eggs)

3 Spiders 50% Het Albino
3 Normal/Wild Type Appearing 50% Het Albino

The 50% only applies to the chance of each egg actually carrying the albino gene. The ones that are ACTUALLY het ARE carrying the gene.... there isn't a % on the gene itself... You would have to raise up the female spiders in the clutch, and breed them back to the male 100% Het Albino to find out who's actually carrying the albino gene.... Until then, you would have Spiders 50% Possible Het for Albino.

Hope this clears things up...

ok so i breed the 100% het albino into a spider, i will get a 50% spider and 50% het for albino babies posibility,(how ever it works out), i raise all 4 babies and breed them back into the 100% het albino parent so i should end up with atleast 1 albino (hopefully spider albino)? am i getting this right or just way off?

the animal either has the gene or doesn't, when they say it is a 50% het, that mean that it has a 50% chance of having the gene, if it does carry the gene then it has 100% of that gene,if it doesn't then it has 0% of that gene, you .can't have a percentage of a gene, it is either there or not

Spider is a dominant gene.... so there will be no percentage on the spiders.... Raise up the female spiders from the resulting clutch (assuming you have a male 100% Het Albino that produced 'em) and breed him back to the female daughters.... Here's what you'll get from THAT pairing (4 eggs)

1 Spider Albino (1/4 Chance)
1 Spiders 66% Poss Het Albino (1/4 Chance)
1 Het Albino (Normal Looking) (1/4 Chance)
1 Normal (1/4 Chance)

(The Het and the Normal will both be considered 66% Poss Het Albinos, the normal appearing Spider will also be considered 66% Poss Het... and hopefully you'll hit on the Spider Albino on the first try... and then.... you hope it's a boy! That way you can raise up that boy and breed HIM back to his parent.)

ok that is about what i was wondering. ok as far as it being a male, why should i hope it is a male albino spider, is it for the shortest to maturity for breeding? or do males pass the genes on better?

oh and how can you or anyone be 100% positive on hets?
