The following distribution of offspring was observed: blue wings, green eyes 1,070 blue wings, black eyes 177 red wings, green eyes 180 red wings, black eyes 1,072 in a particular species of mammal, blue wings (b) are dominant to red wings (b), and green eyes (g) are dominant to black eyes (g). based on these data, what is the recombination frequency?

0.14

Explanation:

to calculate the recombination frequency, you divide the recombinant offspring by the total offspring

thus recombinant frequency = (177 + 180)/(1070 + 177 + 180 + 1072)

                                               = 0.14

"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."
