Biology - December 2007

That is, only rarely does the child of a light-skinned person and a dark-skinned person come out light. And I've heard somewhere that whiteness is actually a recessive gene. If anyone has any information on this or could direct me to some good books or articles, it'd be much appreciated.

...,int design people claim that natural selection and mutation can't account for the complication of life forms, but does evolution even try to claim that it is the harbinger of every facet of a life form (like complication)? Im writing a podcast on "why creation, evolution, and intelligent design isn't mutually exclusive." Any ideas would be highly appreciated! '

thx, Tom atoms55@hotmail.com

True-breeding tall red-flowered plants are crossed with dwarf white-flowered plants. The resulting F1 generation consists of all tall pink-flowered plants. assuming that height and flower color are each determined by a single gene locus, predict the results of an F1 cross of the TtRr plants. List the phenotypes and predicted ratios for the F2 generation.

Some people beleive that in evolution and not god, im one of those people. its said that we evolved from monkeys and they evolved from some other stuff but does anyone actually think thatus humans will evolve into anything?

"There does seem to be a general agreement that evolution 'happened' and is 'happening', but no one seems to have a very clear idea as to exactly how evolution works. While reading these quotes, I think that many will get a sense that even those who are in the know and who ardently believe that evolution happens are still unclear about exactly how it happens. This is interesting because the general public has been led to believe that the very process of evolution is clearly understood by the scientific community."

In Labrador dogs, the dominant gene B determines black coat color and bb produces brown. A seperate gene E shows dominant epistasis over the B and b alleles, resulting in a golden coat. The recessive e allows the expression of B and b. Determine gene types
a. Golden female(dog 1) X golden male (Dog 2)
offspring - 7 gold, 1 black, 1 brown
b. black F(dog 3) X golden male (dog 2)
offspring 8 gold, 5 black, 2 brown
