My understanding is that the universe has no borders, no edge, and if you could somehow cross the entire universe you'd end up where you started (sort of like Asteroids for Atari, but..not exactly).

So, while you could say the universe has no center, wouldn't it be just as accurate to say that every point could be considered the center?

I'm stuck on one of my homework problems where I need to find whether the infinite series of sing(1/n)/n starting at n=1 converges or diverges. I think I have to use the ratio test since it is arbitrary but I'm not sure.

is C*xC* isomorphic to C* if yes prove it

ok so i started with
say just using & as a variable say phi or alpha
so &: C*xC*----->C8
then &: (a+bi,c+di)------->((a+c)+(b+d)i)
and i know i have to prove that it is one-one and onto and preserves operation

to prove one-one have to prove
that if &( a+bi,c+di)= &(e+fi,g+hi)
then (a+bi,c+di)=(e+fi,g+hi)

am i on the right track or totally wrong?

a wild type fly is heterozygous for gray body color and normal wings is mated with a black fly that has vestigial wings. The offspring have the foloying phenotypic distribution:

wildtype: 778
black body vesitgial wings 785
black body, normal wings-158
gray body, vestigial wings-162

In another cross a wild type fly is heterozygous for gray body color and red eyes is mated wtih a black fly with purple eyes. the offspring are as follows:

wildtype: 721
black body, purple eyes: 751
gray body, purple eyes 49
black body, red eyes 45


Q: what fruit flies(genotypes and phenotypes) would you mate to determine the sequence of body color, wingsize and eye color geones on the chromose.

I have the answer has purple vestigial x hetero for p and v, but i'm not sure iff that is correct. please explain how you get the answer
