I'm great with computers But genetics!!!.............. I need some help

herpme Aug 27, 2003 01:38 PM

I am thinking about buying some corns and wanted to know how to figure out what happens when I do this.

Breed 2 snow corns together I don't like assuming things but I guess I would get snow corns.

An albino (no black pigment)male with a snow female
and vice versa.

I know I sound like an idiot but I never did good in biology
But damn can I program.

Thanks in advance../

Actually genetics is very similar to programing! I am sure with the right book/site you'll get it!
Anyway, yup, snow x snow you'll get all snows

anery x snow (no matter who is male or female) would produce anerys het amel, unless the anery is het amel then you'd get half snows and half anerys het amel. What helps people a lot to understand is the fact that "snow" is not a mutation in itself. A snow corn is an amel and anery in the same animal so it needs to be homozygous for both genes. Hope that helps!

Carol is right; genetics is pretty easy to turn into a program. I've seen one named GnP that was programmed by a high school kid for a science fair project.

Genes come in pairs, so the simplest set up is one pair of genes in the male and one pair of genes in the female. IOW, two arrays with two elements each. Array #1 contains male gene #1 and male gene #2. Array #2 contains female gene #1 and female gene #2.

The object is to match each gene in array #1 with every gene in array #2. Two for loops with the second nested inside the first will do it.

Final result is four pairs of genes:
1) male gene #1, female gene #1
2) male gene #1, female gene #2
3) male gene #2, female gene #1
4) male gene #2, female gene #2

As Carol wrote, to work with snow you must deal with two pairs of genes in each snake. That is a bit more complicated than working with one pair of genes, but it can still be done using arrays and nested for loops.

www.geneticswizard.com doesn't really explain the snow thing, but if you already know what snow is, it's a handy little calculator.

Thank you all for your help.

p.s sometimes I don't even understand programming
