Refer to the cross done in the interactive exercise on linkage to answer this question. If, when counting the F1 progeny, you did not separate the two nonrecombinant (parental) progeny classes by gender, hypothetically, how many of each nonrecombinant class would then be present in those two groups?

A. There would be the same number in each nonrecombinant class grouping.
B. There would be twice as many in each nonrecombinant class grouping.
C. There would be half as many in each nonrecombinant class grouping.
D. There would no longer be any nonrecombinant flies to count.

"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."

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.

the answer would be   10%
