a good source for basic genetics?

You need "The Genetics of Chicken Colours" by Sigrid van Dort and David Hancox http://www.chickencolours.com/pagina3.html

Excellent, well laid out book, with lots and lots of drawings and photos to explain and illustrate everything.

The book itself is very expensive though, though I definitely think it is worth the money!

E gene dominance is in the following order:

E > E^R > E^Wh > e+ > e^b > e^Wh

Note that wheaten is listed twice. Generally it is third in dominance; but when additional melanizers are present, it becomes most recessive. The carot (^) indicates that the following letter are superscripted; a + indicates wildtype; capital letters indicate a dominant allele, lowercase letters indicate a recessive allele. Wildtype is the set of genes present in the red jungle fowl.

Chickens have 39 chromosome pairs, cats have 19, rabbits have 22, horses have 32. Couldn't find any sources that listed the number for lepard geckos.

Play with the chicken calculator, check out Henk's Basics page and go from there.

I have found a book that is at least helpful in listing the different color pattern genes and how they combine to make different varieties. I don't completely understand it all yet but it has helped me. The book is An Introduction to Color Forms of the Domestic Fowl by Brian Reeder.

my favorite gecko calculator isn't working... http://www.leopardgeckomorphcalculator.co.uk/MorphCalculator.aspx

man, i can't find out how many chromosomes the gecko's have, but i know there are over a thousand morphs... like, i bred and i guess i'll still breed R.A.P.T.O.r. leopard geckos... that stands for Red eye, Albino, Patternless, Tremper, Orange... the red eye comes from the eclipse gene... on a non albino, it makes them have an all black eye, or snake eye... partial snake eye is called an eclipse... throw in tremper albino, and the eclipse eye turns ruby red... then you have to throw in the patternless gene, and the orange gene... they are hard to make from wild or fromscratch, but i had an easy time breeding an R.A.P.T.O.r female to my mack snow albino giant to create, mack snow super raptors, mack snow giants, mack snow raptors, super raptors and other morphs worth about 150-200 bucks each...


it's a trip... check out the wiki... http://www.leopardgeckowiki.com/index.php?title=Main_Page



sorry for the derail... but i like genetics, and leo's were a blast to learn about... next, i'm gonna try to breed diablo blanco leopard geckos... google them...
