Health Science 101 Guidelines
Greetings! Welcome to Health Science.
Here's where we talk about the latest fad diets, the advantages of vegetarianism, the joy of exercise and good health. Like everywhere else at Tweb our decorum rules apply.
This is a place to exchange ideas and network with other health conscience folks, this isn't a forum for heated debate.

Unless both parents carry a trait it's very easy for a given child to not have that trait. Even if both parents carry it, it may not be expressed in a given child. The only times a trait is certain to express is if both parents have it and neither has a recessive gene for it - or both only have recessive genes for it."He is no fool who gives what he cannot keep to gain that which he cannot lose." - Jim Elliot

There is one gene that we know of that's passed BRCA1 and 2 from mother to child which is a cause of breast cancer BUT Mothers don't necessarily pass it. Even in situations where we might see children with Tay-Sachs disease (such as both parents have the gene) realistically its only a one in four chance that they will have a child with Tay-Sachs. Diseases where there is a specific inherited "mutant genetic cause" are actually quite rare and not all children will inherit them . Its not like eye color by any means. Although when you go and look at the specifics of eye color, you can have multiple generations of parents with one color of eyes and then bam, end up with several children who have different color eyes due to either genetic alterations or intermarrying with a family that has genes for the expression of other eye color.A happy family is but an earlier heaven.

This primary cancer, on the last website I read, has a 40 chance of being inherited. Given the family history...A happy family is but an earlier heaven.

Originally posted by Catholicity View PostI think the best comparison would be the BRCA gene. If both genes are inherited then the female child has a certain percentage of getting breast or ovarian cancer (its rather high in comparison to general population) However even if both parents are carriers its also possible that a child could 1) not recieve the gene markers, or recieve only 1 genetic marker or receive both genetic markers and still never get the disease because something something else has caused the genetic markers to "turn off" or not express at all. Genetic expression is never totally finite when it comes to inherited diseases it seems It appears to take two copies of a gene in the correct sequencing and they must both be of a dominant profile appearing in all chromosomal strains.I am become death...
