I hope to borrow someone's rooster for as brief as I can to breed. The Yodelling will get me arrested, so brevity is necessary. I'm hoping a day or two will do.

One of the questions from my homework states:

"In Drosophila fruit flies, a cross between a dark-bodied fly and tan-bodied fly yields 76 tan and 80 dark flies. Which trait is dominant? Explain. Based on the ratio suggested, use the letters "T" and "t" to diagram this cross."

I am not sure whether the trait with more occurence is the dominant one or not, and I also don't understand how to diagram the cross. Can someone help?
