In Reply to: Jungle Is Polygenetic..... Short Genetics Review posted by LeosAnonymous on May 03, 2003 at 22:19:00:
:The jungle pattern IS poly genetic...
:Many may argue that it is a recessive trait, and in a way this is true. Any trait that is not "wildtype" is recessive to the wildtype trait.
:Here is the kicker... jungle is not a SIMPLE recessive (as in mendelian genetics). A simple recessive trait refers to a trait controlled by one single loci. The term "het" is in reference to simple recessives. When dealing with breedings regarding a simple recessive trait a punnet square can be used to determine the expected ratios of your offspring (both phenotypic and genotypic).
:Wildtype: WW
:Het: Ww
:Albino: ww
:If I was to try and make a comparison to humans I would say that jungle is much like having blonde hair. Two parents with blonde hair have a GOOD chance to produce babies with blonde hair. If one parent has blonde hair and one has brown hair, they still have a better than average chance to produce children with blonde hair. If both parents have brown hair, their children will probably not have blonde hair, but its still possible.
:Now lets take a SIMPLE recessive trait in humans... down syndrone.
:If both parents have downs then ALL of the babies will have down. If one parent has down and the other is het for down (is a carrier but does not show the trait phenotypically) then half of their babies will show downs and the other half will be carriers, etc...
:I appologize if any of this seemed confusing, but its very hard to type out this kind of thing.
