Gene Predictor?

Question

Is there a web site where you can input yours, girlfriends and if need be parents hair / skin / eye colour to predict a childs?

"so the chances are that if one of you is blond/e and blue-eyed and the other is dark with brown eyes, only 1 in 4 of your children will be blond/e with blue eyes, the other 3 will be dark" ..... Ha! thats exactly the case! ok i'll try these punnett squares, yeah i know it's not definate, just main probability

Answer 1

You are crazy if you want to try doing Punnet sqares for human genetics, only do them for blood type, that is the only genes you'll be able to do on a normal sized paper and without so much trouble. Actually, human genetics is basically the same as the Mendelian genetics with peas that they teach at school, but repeated a lot of times. Blood type determination is a variation of this Mendelian genetics: A and B are dominant over type 0, but A and B do not dominate over each other, so they are both presented, hence blood type AB. But in advanced genetics class, you learn that all human genetics are poligenic, which means that there are more than 2 genes (each with 2 alleles) that determine the characteristic. For instance, skin colour is determined by 3 genes and hair and eye colour by 14 genes. If you do the Punnet square you'll get a lot of possibilities, and that would be only for one trait, you would have to do a lot of these, then combine the possibilities and you would have millions of possibilities combining your previous results with the other traits. Also, you would have to interpret each result, because although some would be genetically different, the phenotype, or the way the "child" would look would be the same. Believe me, you'll go nuts, I had to do a skin colour Punnet square, and it was horrible. Doing a hair or eye colour square would be a possitive nightmare.
What you can do is look at things from a different angle. If your skin colour is light, and your girlfriend has a very similar skin colour, your "child's" skin colour would be somewhere between a tiny bit darker than your own or very white, and you have bigger chances of your child being somewhere in the middle. The same happens with hair and eye colour, but these can have two shades at once.

Answer 2

Not that I know of, but the genes for dark hair and eyes are generally thought to be dominant, so the chances are that if one of you is blond/e and blue-eyed and the other is dark with brown eyes, only 1 in 4 of your children will be blond/e with blue eyes, the other 3 will be dark.

Answer 3

Yes punnet squares are good but you need to remember heritable traits are totally random. There is no real way of knowing which traits will make themselves apparent. You can only use punnet squares to see what might be more likely or the percent chance of getting one trait over another.

Answer 4

Unfortunately, most traits are NOT predictable. In fact, most of what people believe about traits is precisely wrong. For example, if two parents who are 10% above average height have a child, their child is more likely to be LESS than 10% above average height.

This is because most human "traits" are determined by, not one or two, but many different genes as well as the environment while developing.

Only with simple traits (determined by one or two genes) can you predict a child's traits. However, these simple traits are very rare indeed. For example, the "mid-digital hairs" (MDH) trait is simply inherited. The chance of having hairs on the back of the middle bone of your fingers is completely predictable, as is whether you are able to curl your tongue lengthwise. However, I doubt many parents want to know these things.

Answer 5

gay adult men inherit the features from their mothers. The "gay gene" escapes organic decision because of the fact on an identical time because it inhibits a guy'a potential to reproduce it will develop it in females. for this reason, females who carry it are possibly to be greater promiscuous and involved in male bodies. it style of feels to be linked with features which incorporate extraversion and openness in females which makes adult men greater involved in them. not all females with this gene might have gay sons. It randomly takes place the two a male or woman gets it. the former will grow to be gay and without reproductive success the gene itself will die out. The latter is understood to grow to be very involved in male bodies and it will set off alluring features that stand out to adult men ideal to reproductive success and reinforcing it.

Answer 6

Research how to do Punnet squares.
They would tell you PROBABILITY only.

Answer 7

I really dont know but it would be interesting,i wonder what the punnet squares are all about.
