Using pea plants as an example. Characteristics of an organism is determined by a pair of factors. If the two factors are different, only the dominant will show effect.

1) Regarding the pair of factors, is one from each parent?

2) And also, is it possible that the dominant allele is the trait for shortness? Cause it's often said that T (tall) is the dominant, and t (short) is the recessive... can it be vice versa?

If i read one more question with that as its basis i will go crazy. Charles Darwin never said that. We have a common anscestor, but we split. We are not evolved from apes! But no matter the number of times people are told, there is always another question asking the same thing!!

An old retarded atheist came up with a silly theory and now millions are consistently finding ways to keep this theory alive. Is there a motive? We keep finding species that were thought to be extinct and even with modern technology still no "missing link". I have read the origin of species and fully believe that if the retarded old guy was still alive he would concede he was wrong. The saddest is that Darwin's friends are still trying to keep the theory alive with silly subsequent theories such as punctuated equilibrium. Is it too hard to admit that we have no idea how we came to be. The hoaxes are so pathetic - Piltdown Man, Nebraska Man, Urey/Miller. This is not a religious question and I am not talking about evolutionary processes that are provable through scientific methods.

This may be a stupid question, but what is the Internet for then?

It is both to pose inteligent questions, and questions which you would risk losing your face if you posed them in real life.

This was inspired by a question that someone else asked.

In our societies, and specially nowadays, it is indispensable to take a bath everyday. (And let me say I do observe this, and also that there have been times on which I even had 3 showers on the same day...)

But just out of curiosity, I've always had dogs, and we never wash them more than once a month (as a matter of fact, in Winter I wouldn't say we wash them that often).
My mother used to say that washing a dog too often damages their hair, and whether this is true or false, they don't seem to smell. (At least, I rarely realize that... and when they do, it's because of tartar in their mouths...)

So, does this mean that humans are more prone to develop bad odours if they don't take showers often, than other living things?
