Thank you very much for this thread, have spent the last few days head scratching trying to figure out what BRB meant as all i could like of was 'be right back'...and I also could never figure out what the numbers meant near the snakes people list as owning.

Thank you for making it all make sense

Default het

Hi, sorry to sound completely stupid, but could you explain het again - have read it over and over, and its really bugging me now!!! Could you explain it in regard to corn snakes, for example? Thankyou

het means invisible gene. as an example you look at amel/ albino corns.

in order to look like amels they must have 2 of the genes that code for amel, which i will call a.

a normal corn doesnt have this so his genetics are NN.

a het amel corn is a corn that has one of each - so Na. because the normal gene is dominant. this means the visual characteristic that the N gene codes for is the one that is shown in the snake - this is also called phenotype. the gene a which codes for the amel trait is recessive, which means that other genes mask its appearances - which is why you need 2 of them and no normal for it to be visual.

does that make sense? its extremely simplified - essentially

normal = NN
amel = aa
het = Na

Het means only and exclusively that the two genes of a pair are different. Think "heterozygous" like "heterosexual".

A pastel royal python is het pastel, het not pastel.
An ultramel corn snake is het amel, het ultra.
A motley corn snake can be either homozygous motley (two copies) or het motley, het stripe.

Better to say that "normal not Amel" is A - so that it's obvious that A goes in a pair with a but does not go in a pair with M for not-motley or H for not-hypo.

For example, my Coral Snow het Bloodred is best expressed as:
aa Dd ee hh
That's homozygous amel, heterozygous diffused, homozygous anerythristic, homozygous hypo.

firstly my post was a clear oversimplification, and to describe het as having an invisible gene is a good simple way of describing such an animal in the hobby.

in your example - whilst your way of expressing may make sense to you and i, for someone new to genetics you may as well use chinese characters. so instead of going and explaining it as you have i feel it alot easier and simpler to understand if you explain it as i did, in which case clearly the phenotype of the individual is of course Coral snow, whilst the heterozygous aspect means there is a single gene that is unable to express its phenotype, therefore resulting in a het bloodred coral snow.

its differant methods of explaining, but i think for someone that isnt clued up with genetics my way offers an adequate explanation. you dont teach algebra to 4 year olds in maths classes
