DO YOU KNOW THE ANSWER, BIOLOGICALLY? BECAUSE MY HUSBAND HAS RECEIVED A PATERNITY PAPER FOR SOME 15 YEAR OLD CHILD FROM A ONE-NIGHT STAND AND THIS CHILD HAS BLUE EYES AND HE AND THE MOTHER HAVE GREEN EYES!!!

Eye color is controlled by many genes and it's not as simple ... what you were thinking.

Check out (scroll down to "genetics" and read): http://en.wikipedia.org/wiki/Eye_Color

the bottom line is ... have a paternity test done... that's the only way to be sure. (albeit, and expensive way!)

best wishes!

check out this "eye color calculator" (it probably won't help you in your situation)

http://museum.thetech.org/ugenetics/eye ... lator.html

when you use the calculator... the percentages in the bottom row of boxes represents the probability of a child having a particular eye color.

lilkim is right. In theory, the child can be your husband's. According to what is known about eye color now this is a possible scenario.
Both your husband and the supposed mother are homozygous recessive for the gene for brown or blue on chromosome 15. And they are both heterozygous for the blue or green gene on chromosome 19, since green is dominant to blue at that locus. When the supposed child was conceived, he inherited the allele for blue eyes from both parents on the locus on chromosome 19.

So this doesn't help you. Get a paternity test done.

hmm??? Not sure? I worked on mine....

here is how I found it:

1.) go to: http://en.wikipedia.org/wiki/Eye_color
2.) scroll down to the bottom where it says "external links"
3.) Click on the first link: "What Color Eyes Would Your Child Have?"

Work with firefox here. But maybe you have some security enabled or not downloaded a plug-in that prevents firefox from running the page.
