LOL..We did that in Freshmen year of Biology? You don't know how to use it!?....wow
Not everyone learned the Punnett Square. As a matter of fact, I didn't learn it until after I was out of school.
I didn't even have biology in my HS..
assumeing they are full brother and sister and she doesn't show the characteristics she is likely at least a carrier.. you'de have to dig back further to get any real solid numbers but the punit square works pretty well for giveing good generals. If in fact she doesn't show the characteristic means it's likely recessive... so you would have a double recessive gene in the male.. and a recessive and a dominant from the female. so you're looking at approx 25%/50%/25% double negs liek the male to degress of carriers and non-carriers. But I could be wrong.. not sure if female bettas may just not show the gene but are double negs... You would have to talk to a betta breeder. also depends on the amount of inbreeding in the line sometimes as well how strongly a particular characteristic may show.. or vanish. To much inbreeding will often result in small batches, and weak fish. Reguardless of all of that it would be a fun experiment to make.
if they both come from the parents u listed and they don't show dt and dt is rececive then there is a 50% chance for each one that they are heterogeneous. there is also a 25% chance that they aren't
They had a relatively small batch but they were both inexperienced. That was the first spawning for both of them and young. They have 15 fry right now. And it's possible some of the eggs were eaten. They started spawning at about the same time I had to go to church. This is as far "inbred" as I will go. I wanted to see if I could get a double tail from them. And if I do I'm going to find another white double tail to breed that offspring to and one that's a regular plakat. It's said that breeder often breed regular in the line to strengthen the line. The breeder I got them from has the genetic line going back 5 generations. The male (their father) was a double tail and the mother was a regular half moon plakat bred in for "strength". The first generation he has info on was DT DT, the second was DT male of that spawn and (ST) female of a sister spawn (the mother's sister's daughter). The third was a (ST) female of that spawn and a random (DT)male plakat. Then the Father came from that line and the mother from another line. And then my 3 Betta's. He's asked me not to say anything about the line other than to state what they were.
And I didn't do Punnet Square. I took high school physics in place of biology. (I can't do animal biology because of having to dissect).

Kay. If both parents are heterogeneous for double tail on their father's side and I breed them together what's the ratio of DT to ST (single tail) fry I will get in about 15 fry. Also if I breed THIS fish: http://www.youtube.com/watch?v=i24PG...eature=related with the fish in this video seen at 4:45 http://www.youtube.com/watch?v=nUuhZHQUGLc could I posibly make a black and white Butterfly, or a contrast black and white fish?
Betta's. Both are at least half moon plakats.
You first need to determine if double tail is dominant or recessive, and then you can approximate what your offspring will be in any scenario. It also may be a bit more complicated than a single gene with a simple dominant/recessive Mendelian pattern.
To answer the second question, again it depends on the inheritance pattern for colors. Perhaps someone here with some experience breeding bettas can chime in.
I"m starting to think I'll just have to wait and see. Can anyone reverse engineer this for me (The second one)? What two Betta's are MOST likely to get this outcome? What type of fish do I need? What needs to be dominant? Would getting two black and white marble Betta's work, two black and white butterflies? If that color would be hard what color would be easier. I want the end result something like this: http://www.youtube.com/watch?v=-kCLjUOoNTc
really???? hahahaha man u are talking about generatons of selective breeding to get a strain that is like that or even if u are just wanting 1. or the other option is just plain dumb luck. and when i say this i am breeding many at a time picking the ones with the desired traits and so on and so forth.... until u get what u want. for all u know it could take years and years.
2 years actually. The video comments say so. And I'm not above taking years to accomplish this. So calm down. I just need to know where to START.
