Determining The Chances Of Inheriting Genetic Disorders

Often, genetic disorders run in the family. Depending on the type of gene mutations that occurred in the genes, the risks of passing the illnesses on to the next generation vary. Mostly, the risks of developing a genetic disease can be hard to determine because other factors such as the environment play a role.

At any rate, the pattern from which genetic disorders are obtained can be a determining factor. There are six ways that a disorder is inherited, namely the Autosomal dominant, the Autosomal recessive, X-linked dominant, X-linked recessive, Codominant, and Mitochondrial.

People who are afflicted by Autosomal dominant inheritance have 50% chances of passing the mutated genes to their children. Children who have parents with Autosomal dominant diseases have 50% chances of not inheriting the mutated genes.

In Autosomal recessive inheritance, two individuals who do not suffer from a genetic disorder, yet each carriers in his and her cells a copy of the mutated gene have 25% chances of passing the genetic illness to every pregnancy. With each pregnancy, the chance of having an un-afflicted child who carries the illness is 50%, while the child's chance of not inheriting the disorder and not being a carrier of the mutated gene is 25%.

The X-linked dominant inheritance has striking difference in passing the disorder because men have XY chromosomes while women have XX chromosomes. A father's Y chromosome is passed on to all his sons and his X chromosome is passed on to all his daughters. Thus, the sons whose father has an X-linked dominant disorder will not be affected. However, the daughters whose father is affected by an X-linked dominant illness will also inherit the disease.

On the other hand, one or the other of a woman's XX chromosomes can be passed on to each child. Thus, the chance of a woman affected by an X-linked dominant disease to pass on similar disorder to every pregnancy is 50%.

In X-linked recessive inheritance, however, the chances of passing the disorder vary because of the variations in sex chromosomes in a way that sons whose father has the X-linked recessive illness will not be affected, while daughters will inherit one copy of the mutated gene. In each pregnancy, a woman affected by an X-linked recessive illness has 50% probability of passing the disorder to her sons, and 50% chances of passing one copy of the mutated gene to her daughters.

Each parent affected by Codominant inheritance has a varying version of contributing a specific gene. However, both versions have an impact on the resulting characteristics of the gene. Therefore, with Codominant inheritance, the chance of developing genetic disorder and the characteristics of that disorder depends on which version of the gene is passed on to the child from parents.

The genetic disorders obtained from Mitochondrial inheritance are a consequence of mutations in mitochondrial DNA. While the illnesses can affect both men and women, only women can pass the gene mutations in mitochondrial DNA on to their children, regardless of the sex. However, men who have Mitochondrial inheritance of diseases cannot pass on the mutated genes to his children.

Other than the inheritance, the chances of obtaining the mutated genes can also be affected by an individual's family history and the results of Genetic test.

Poor qualities = no franchise! - Most franchises screen their potential franchisees very well (and if they don't, then they aren't a good franchise). Chances are if anyone held even some of the qualities you outlined here, they would not be granted a franchise. Just because someone has the cash to purchase one, doesn't mean they will get one. And Nana- you are so right, no one should be in any type of business if they hold those qualities!
Re: Note to Mods - Sneaky Spammers... - Another few quick tips... If someone joins then starts a new thread(s) right away with any sort of self-promotion in them, it's most likely a drive-by poster (spammer). This is especially true if they don't at least give an introduction first, or come back after a day or two and actually participate in the forum legitimately. Truly legitimate users don't do that stuff. Sometimes people make mistakes at first then end up being good members, but not often. This might sound mean but don't give any potential spammer the benefit of the doubt. FAR more often than not they will never become a useful member of the forum, so we don't want them here. I've been moderating several forums for the better part of a decade and I can tell you right now it's better to just delete a post you are unsure of rather than leave it. Chances are that if you have any doubts about it at all then it needs removed. Call me a hardass if you want, but I hate spammers!
How to get links to your website - Thanks for the post Barbara! I wrote back in my response: [quote:2ar0xqpw]the trick with Wikipedia is that the link has to be of genuine value. If it’s obviously just a related link then you’ll get removed. If it’s adding serious value to the post then it’s more likely to stay on - but even then you can have an overbearing administrator who removes you. I’ve also found more luck with less popular pages than the ones that are constantly being update. Chances are you can add more value to a page that hasn’t had as much work and the link will stay. Good luck![/quote:2ar0xqpw]
Re: How to do Link Building? - Hi Members, You have all given some fantastic feedback on this subject and the combined effort of using all of these techniques will surely bring great benefit and I haven’t really got a lot to ad other than one thing which GT has already touched on earlier. That is to type your keyword phrase into Google and list all the sites on page 1 and even 2 and visit them all in turn. Chances are most of them will have articles of some sort and it they have a comments section then jump on it. Leave a meaningful and useful comment (you don’t want it to be removed by the site moderator) as you want to ad useful content to the article and not devalue it. In your comment you can leave a link back to your site and there you have quality backlinks form high ranking sites, regards, Mal.
Women Win - Hey there! I think that women are better at multi- tasking. Now that doesn't mean men can't or don't multi-task. I think it comes down to the environment you are raised in. Traditionaly it was a womans job to take care of the kids, the house, the husband and in some cases the money. Since that was the case it was neccesary for us to be able to get more then one thing done at a time. Like Ryann said it is more of a survival instinct then anything. Some studies do show that multi-tasking takes away from what you are doing. However, I think it depends on what you are doing. For example I saw a picture yesterday randomly of someone in a park reading a book and texting. I would say this is a bad way to multi-task. Chances are you will forget what you were reading and have to go back to read it again. What about when its time to do laundry and food shop? I always put a load of laundry in when I am on the way out the door and then while my fiance brings in the food I am flipping the loads. Then we proceed to put the food away. By the time this is done so is the first load of laundry to be folded. Is this an ineffective way of multi-tasking? I don't think so at all. Why not get two things done at once. So long as you aren't taking away from either of the tasks at hand. Liz
