Genes

[Jam930]

There are dominant genes and recessive genes. Genes of parents...come together....dominant genes rules...these dominant genes...hm. This means that eventually all girls will look the same. and all boys will look the same. we know this. all the people from scandinavia look more alike that people from scandinavia vs papua new guinea.

Doesn't this contradict the theory of evolution?

In some aspects, yes it does. You see it with similar facial features among people. Jewish people having large noses, Mediterranean Europeans have darker skin than northern europeans etc.

But this brings up the question of where those genetic traits were developed. Most scientitsts say they've adapted to their habitats over thousands of generations of evolution. Today, we control our environment for the most part and we, in theory, will develop different traits.

However, recessive genes often pop up. For example, a white woman in the states had twins. One of them had black skin (they did the DNA tests and everything and he was the son of a white woman and white man). This supports the theory that the first homosapien (Known as Eve) was somewhere in africa. She met up with another homosapien and they mutliplied and spread out across the world.

meh.... thats not true. ill just say this. durring meosis the chromosomes unravel and crap.

after that when they split and copy themselves. durring this process randomly,

little sections are crossed creating new genes. thats why you can have a sis but not look the same.

l

ittle sections are crossed creating new genes. thats why you can have a sis but not look the same

What about when the little sections dont cross creating new genes,they stay the same therefore twins?

[Jello]

yep thats right. through the history of life on this planet, that has happened. the chromosomes decided to stop crossing.chromosomes dont just decide not to do something that happens naturally, and is uncontrolled.

think back to the thread about "is another me possible"... same princible.

as for the twins comment. twins are caused when the initial stages of the zygote split and then develope serperatly. your body wont decide one day " oh lets produce all the sperm exactly the same!" because it just doesnt happen when your body just wants to pump those suckers out. doesnt take the time to make sure the DNA is the same like in mitosis

[RobbyZero]

Twins Triplets and so on is basically random

[Jello]

its random if the zygote splits. the only difference between twins and quads is how many times the zygote splits before it starts to develope.

hm? we know that people living together for a long time, cross-breeding, will start to look more and more the same. Unless some foriegn genes enters the picture, people will continue to look more and more alike, as the dominant genes take over. blue eyes or brown eyes? brown eyes = dominant, so eventually everyone in a certain area will start to pickup brown eyes over blue. this idea explains why...

the people from scandinavia look more alike that people from scandinavia vs papua new guinea.

so im saying eventually the world population, after a million years of mating, would all pickup the dominant gene and we'd all look pretty similar.

and this kinda goes against evolution.

(Known as Eve) was somewhere in africa. She met up with another homosapien and they mutliplied and spread out across the world.

now that...well. you'd have like 2 humans to start with i suppose...meaning one VERY small genepool. see how could u get recessive genes from ancesters that also had the dominant? recessive genes are lost through time. and type O blood is also recessive, but among westerners its most common...where did A, B and AB come from? mutations? i dont know, but it certainly isn't evolutionary.

why not?

[makaveli121212]

Hardy-Weinberg, thats all you need to know about recessive genes in a population...do a google search for it...common knowledge

[DracIV]

Simple answer: The dominant genes aren't the ones always passed on. It all depends on how unlucky you get whether or not we all look alike, and even then there will be different people who got the recessives.

[makaveli121212]

trust me the guys i posted above proved how the recessive genes stay in the population...your question is flawed jam...humans didnt start out with just one blood type by the way...considering we evolved from other primates, they also had different blood types...most of the first humans and very very similar DNA to the apes, etc. Most of human DNA is the same if not close to the same as apes, etc. Blood type is definately evolutionary

refer to punnet squares.. someone with Bb crossed with someone with Bb for brown eyes over blue
B= brown eyes
b= blue eyes..

when solved its a 25% chance of BB; 50% chance of Bbl; and 25% chance of bb;

meaning that there is still hope for use blue eyed peoples...

and also, it has to do with genetic mutations, and things of the sort... eventually, like WAY down the road, there will only be one race of person.. no more whites, blacks, asains, indians, we will all become one race eventually... but never will we all look the same.. there are just too many elements that go into to physical features of people to get us all to look like identicals
