I know that a sex cell only has halve the information I thought I made it clear in what I saidBGH122 said:This is incorrect because only half of the genetic information is included in each sex cell to be used in meiosis. So it's much likelier that, in a family with a recessive negative trait, two siblings, both of whom potentially have the recessive trait, could have the recessive trait packaged in their sex cells. With the general population the likelihood of meeting someone with the same recessive trait and having it end up in the sex cell which is used to create your zygote is far lower than with siblings.nuba km said:OK guys simple biologie for people most genetic flaws are recessive (r) genes meaning if you have a dominant(D) gene you aren't affect by it but carry this is why something "skips" a generation they get a (D) gene from the other side of the family. so if you are were (r)(D) blue eyes (presuming blue eyes are recessive) are concerned and your sister/brother is the same (r)(D) your child gets one of the two genes there are four outcomes (D)(D) your child doesn't get it at all (r)(D) there are two ways to get this outcome or(r)(r) meaning your child has blue eyes. this is the same for genetic flaws it doesn't matter whether you sister/brother has it or some stranger has it your child has the same chance of getting it either way.
NOTHING SPECIAL HAPPENS WITH INBREEDING IT'S JUST THE CHURCH SAID SO THEN SOME EARLY SCIENCE THAT DIDN'T FULLY UNDERSTAND GENES DID SOME EXPERIMENTS THAT AT THE TIMED PROOFED IT AND THE GENERAL PUBLIC LIKE IN MOST CASES HASN'T BOTHERED TO CORRECT THIS FLAWS BELIEVE.
also your sibling my not even have the gene at all because lets say the dad had two (D) genes and the mum had (r)(D) meaning it's a a 50% chance of one of you having it meaning its a 25% that both of you have it meaning that the likely hood of the baby having it is relatively low. pulse the genetic flaws a lot of people are talking about is quite common these days compared to fifty years ago and that's only the people that have both recessive genes not just the people that have one meaning the likely hood of meeting some one that has the same (D)(r) gene combo is very likely.
