Coral snakes are brightly colored highly venomous snakes with red, yellow, and black bands along their bodies. another species of snake, called the scarlet king snake, has similar bands of red, black, and yellow. which of the following describes the conditions that resulted in a large population of king snakes with these types of markings?

Since king snakes with these markings were avoided by predators, they were able to survive to pass on this trait to offspring.

Explanation:

Given the following choices, B is correct:

A) King snakes and coral snakes relied on similar food sources that contributed to their unique coloring.

B) Since king snakes with these markings were avoided by predators, they were able to survive to pass on this trait to offspring.

C) Coral snakes mated with king snakes often enough to produce another species of king snake with the red, black, and yellow.

D) Overproduction of offspring increased the likelihood that the genetic mutation leading to these bands would spontaneously occur.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
