 And also how do one genetically explain that from normal colour parents you have albino offsprings ???

 What color did the fry turn out corydorasseracin?

They are all "black" but some of them are darker than the others. For sure, there are no albino BN, like the father.

 Would the albino gene be weaker then the normal gene ???? Maybe there is no albino fry like their father ??

martin

well done on the BN's jas, i need to get on the right track again with my fish

Thanks alot Chris.

I'll try & keep some of my fry & within 2/3 years try to breed them. Maybe some albino will pop up, but from 4 batches of fry, I'm sure that there aren't any.

Albinism results from inheritance of recessive alleles. The condition is known to affect mammals (including humans), fish, birds, reptiles and amphibians. While the most common term for an organism affected by albinism is "albino" (noun and adjective), the word is sometimes used in derogatory ways towards people; more neutral terms are "albinistic" (adjective) and "person with albinism" (noun). Additional clinical adjectives sometimes used to refer to animals are "albinoid" and "albinic".

Thanks to wkipedia

Once , when I was much younger I remember there was a girl she had white skin and hair and red eyes.  I couldn't stop staring at her.  Later in the years I discovered what it was (albinism) and I remembered about that girl.  She must have been very uncomftable at me staring at her , but I couldn't help it and I was just a kid

Anyway Charles , thanks for sharing  

 Thanks Charles and Seracin.... Keep us updated mates.

That means that the mother has no albino gene. Since the father is in fact an albino, all of the offspring have an albino gene, however albinism is not exhibited due to the fact that it is a recessive gene. Thus if two fry are bred, the resulting offspring would be 50% albino and 50% 'normal'. If you wish to get more albinos than 'normal' colored BNs you should breed one of the fry to the father to get 75% albino and 25% 'normal'. If the opposite percentages are desired the mother should be bred to one of the fry.

Goodluck

 Thanks for the info corydorasmalta. That is a real challenge seracin. Good luck.

That's what I wrote in one of my previous posts - I'll try & keep some of my fry & within 2/3 years try to breed them. Maybe some albino will pop up, but from 4 batches of fry, I'm sure that there aren't any.

So I have to keep on fishkeeping to see any results.

we will surely wait 2/3 years for your results Seracin.

 As some of you know, I am not very enthusiast with bottom feeders. I have acquired in the past a couple of bristle nose catfish but did not last very long as the water I had was not suitable for them. However, I persuaded myself to have another go. I acquired another pair and housed them in a more suitable water for them. This time not as hard and alkaline as before. They settled in and within a couple of days they were eating and discovering their new surroundings. About a month ago I noticed that the male and the female were frequenting an upside down flower pot placed on a piece of slate in the tank. To cut a long story short, after I realized that the male was eagerly attending the entrance of the pot. I was so curious, and I pulled out the pot and to my amazement I saw about 12 little ones attached to the inside of the pot. I placed them in a separate container with the same pot. Today they are about 2 weeks old and eating zucchini and small sincking pellets. 

I will post a couple of pics very soon.

Well done Martin. Nice to see more fish keepers trying to breed different species of fish.

Do you have other fish in the tank, together with the BN pair?.

 All I have seracin is a pair of Microgeophagus ramirezi which I want to breed. Can you have albino offsprings from a pair of normal coloured Bristle nose ??
