a couple of questions

[cjam]

Ok so Im confused about some genetic terms. When something is het for say albino whats that mean. Also if it is Homozygous what does that mean. And my last question is how do people figure out the percent chance of geting what? thanks

 

[hulker75]

The term "het" is short for heterozygous, meaning it carries a recessive gene, ie albino. The term "homo" or homozygous means it actually shows that recessive gene.

So a "het for albino" looks normal but carries the albino gene.

An "albino" is actually the homozygous form of that trait.

This works the same for all recessive genes.

Co-dominant genes will also work this way..example:
Mack snow being the "het" for super snow
Super snow being the "homo"

Percentages are figured using a Punnett Square. You can google it and there are several different online calculators, sorry for not providing a link.

If you want get the percantages go google genetics wizards, it is an online punnet square. Thats where I get all my percentages.

Hope this helps!

Here are simpler definitions for homozygous and heterozygous:
Homozygous = the two genes in a gene pair are the same.
Heterozygous = the two genes in a gene pair are not the same.

All gene pairs are either homozygous or heterozygous. By extension, the organism possessing a given gene pair is also homozygous or heterozygous.

In modern genetics, the normal or wild type gene is the standard of comparison and is neither dominant nor recessive.

Heres what it takes for a mutant gene to be recessive to the normal gene. An animal has the mutant gene paired with a normal gene. This animal does not show the effect of the mutant gene. The animal looks like an animal that has two normal genes. In other words, the heterozygous animal looks like an animal that is homozygous normal.

Heres what it takes for a mutant gene to be dominant to the normal gene. An animal has the mutant gene paired with a normal gene. This animal looks like an animal that has two copies of the mutant gene. In other words, the heterozygous animal looks like an animal that is homozygous for the mutant gene.

Heres what it takes for a mutant gene to be codominant to the normal gene. An animal has the mutant gene paired with a normal gene. This animal does not look normal and does not look like an animal that has two copies of the mutant gene. In other words, the heterozygous animal does not look like either the homozygous normal or the homozygous mutant animal.

Lots of people tend to ignore normal genes. But when doing a genetics problem, the normal genes are just as important as mutant genes.

Here's a link to the Advanced Genetics Wizard.

Good luck.

ok cool thanks that helps alot. I really appreciate that. I have one more question... Im trying to use the wizard website but I dont think Im doing it right. How would I put in the information if I am breeding a male rainwater hybino and a female normal? thanks again

 

[Gregg M]

The same as if you were doing an albino to a normal...

You will get normal to hypoish looking geckos that are 100% het for albino...

 

[cjam]

Well i mean im not sure on how to use the website. i know that the albino trait is dom. and het, so do i put that there is 1 gene and put the male is het and dom and put that the female is wt?

 

[Gregg M]

The albino gene is not dominant, it is recessive...

You do not even need the wizard for such a simple pairing...

 

[cjam]

oh ok then sorry i was thinking that it was since on the rainwater im getting you dont see the normal pattern... never mind then, sorry

 

[canadiangecko]

yeah Het albino means that some of their babies will be albino
