I have dark brown eyes,my wife has deep blue eyes and both my daughters have crystal clear blue eyes.Someone once told me that if one parent has brown eyes and the other has blue eyes then nine times out of ten-the kids will have brown eyes.I think they were talking nonsense but is there a determining genetic factor on eye colour?

I'm trying to find articles specific to this question, but I don't find what I'm looking for. Need to know exactly how sodium hydroxide and sodium chloride will kill or inhibit bacteria and fungi. I'm sure this info must be out there somewhere because NaOH is the base of many detergents that is used in the food industry.
Give references please.

I know it must vary with the size of the person, but is there a way to guess. Like the way you can guess the size of your heart, because it's about the same size as your fist?

Could anyone give me a website containing data on the classification of bacteria? I need it to complete a homework.

I'm wondering about the affects of slavery,gender bias, hunger etc. Do we affect our own DNA through these struggles and then pass on the result to offspring? Please answer in understandable language...science for dummies. Thanks.

ok, so for a short while you were a sperm inside your dad's body. Where the hell were you before that? still somewhere in your dad's body as a dormant cell? maybe your moms? I want answers. Jesus told me we are all Gods children so what about the trillions of other sperms that don't make it? are they just losers?

seriously though where the hell were you before you were born?

During the prehistoric days, particularly during the days of larger dinosaurs, it seems there was a large amount of biomass on this planet. In comparison, it seems impossible for such large creatures to survive in modern times b/c there isn't enough food for them to survive. Besides habitat destruction, where did the biomass disappear to? Could it have all turned into fossil fuels? And if so, will it ever reenter the bio-cycle?

In my biplogy class, we just finished learning about evolution and Darwin's theory.

I myself, believe in evolution. I believe that it took millions to billions of years for humans to evolve into he way we are now.


I respect Darwin and in my class(I'm in the 10th grade) we did sort of a trial where people were either on the for evolution side or the against evolution side. we picked a scientist or person who supported evolution or who didn't. I was Charles Darwin himself.


I wanted to know what people though about Darwin and his theory. what side are you on?

Hey everyone! I've spent about 3 hrs on this problem and can't seem to find an answer, so here goes:
When yellow mice are mated together, 2/3 of the progeny are yellow, 1/3 are agouti. Another locus is known to govern pigment production. When parents heterozygous at this location are mated, 3/4 of the offspring are colored, 1/4 are albino. These albind mice can not express whatever alleles they have at the agouti locus. A yellow mouse is crossed with an albino and produces an F1 containing 1/2 albino, 1/3 yellow, and 1/6 agouti.

I've figured out that the only way to get the 2:1 phenotypic ratio between yellow and agouti is to consider the dominant yellow allele, when homozygous, to be lethal. I understand that it is not lethal when the recessive albino allele is homozygous. Past that I'm stuck. I feel like I've tried everything!
