Jayba Posted March 22, 2012 Report Share Posted March 22, 2012 (edited) I have a male long fin albino that is brooding some eggs from a calico regular fin female. What should the fry end up being? Ratios and such.....genetics was many years ago. Thanks Edited March 22, 2012 by Jayba Quote Link to comment Share on other sites More sharing options...
SuperGuppyGirl Posted March 22, 2012 Report Share Posted March 22, 2012 I say at least half will be regular fin calicos, a quarter will be long fin calico, around 12 percent will be long fin albino the other 12 percent regular fin albinos and at least 1 percent will make you go WTF? lol can't wait to find out Quote Link to comment Share on other sites More sharing options...
JORG Posted March 22, 2012 Report Share Posted March 22, 2012 you will get no albino's Quote Link to comment Share on other sites More sharing options...
Jayba Posted March 23, 2012 Author Report Share Posted March 23, 2012 you will get no albino's OK, why? Is albinoism (if that is a word) not a dominant trait? I would get 50/50 calico reg fin and long? Quote Link to comment Share on other sites More sharing options...
JORG Posted March 23, 2012 Report Share Posted March 23, 2012 To get albino's both parents need to carry an albino gene, if I remember right. If the offspring from your brood breed with each other they will produce albino's. Quote Link to comment Share on other sites More sharing options...
African_Fever Posted March 23, 2012 Report Share Posted March 23, 2012 There could be the chance the calico could be carrying the albino gene; if any fry are albino, it would answer that question. Albinism is a recessive gene - so the albino make has 2 albino genes, whereas the calico is unknown, and could potentially carry the gene but not show it. I'm not sure if the calico and long fin genes are linked, so can't help w the ratios. Quote Link to comment Share on other sites More sharing options...
ckmullin Posted March 23, 2012 Report Share Posted March 23, 2012 100% of having some number of fry. 100% of being a happy pappy. Quote Link to comment Share on other sites More sharing options...
jvision Posted March 23, 2012 Report Share Posted March 23, 2012 Albinism is the only one I know for sure, and it's been covered here already. Long fin is weird; even LFxLF won't give 100% LF offspring. I know vertically nothing about calico. Basically, what it all comes down to is that the only way to know what you're going to get is to wait and see what you're going to get.

Fisher Posted March 23, 2012 Report Share Posted March 23, 2012 Genetics... Biology 30. Albinism is an absence of pigmentation is due to recessive genes or a simple mutation. The mutation, by definition, is genetically unpredictable. But there is some predictability to genetic pairing. You can use a punnett square to plot the theoretical possibilities. Albino is always recessive so an albino animal is a homozygous albino (aa) genotype. Your phenotype calico can be a homozygous (CC) or heterozygous (Ca) genotype. 1. CC + aa = Ca, Ca, Ca, Ca (all hetrozygous calicos, no albinos) 2. Ca + aa = Ca, Ca, aa, aa (het and albino are possible) All theoretical predictions. You could have a hetrozygous calico parent (Ca) and not see albino offspring. But pairing your calico with an albino is the only way you will learn what genotype your calico is; hetrozygous (Ca) or homozygous (CC). Add fin traits to the mix and you jump from 4 theoretical combinations to 16. Quote Link to comment Share on other sites More sharing options...
