Homework Answers
CROSSBREEDING is the mating of parents from 2 or more different breed.
a. Crossbreeding
It is the mating between the 2 different species, breeds or variety. Species is defined as a group of animals that can interbreed and produce fertile offspring. If the mating occurs within the same genus such as dog but the mating occurs between different species of dog such as poddle and retriever produces the offspring or crossbreed labradoddle.

You cross two true-breeding lines of flies, one line with normal eyes and the other with sepia eyes. All F1 flies produced have normal eyes. If the F1’s are crossed to other F1’s and a total of 1,810 baby flies are produced, how many do you expect to have normal eyes if this trait is due to a single gene showing complete dominance?

Species A has a breeding call that is completely different from species B. This difference in breeding call leads to (A) prezygotic isolation (B) postzygotic isolation (C) coevolution (D) sympatric speciation

Karsh has been breeding two different types of angel fish: a common breed and a rare breed. His 14 common breeds have mean length 3.2 inches with standard deviation 0.4 inches. His 12 rare breed have mean length 3.4 inches with standard deviation 0.3 inches. Create a 95% confidence interval for the true difference in mean lengths between the common and rare fish.

Assume that tail length in white rats is a quantitative trait. In one pure-breeding line the tail averages 7 inches and in another it averages 4 inches. Progeny arising from the interbreeding of these two lines have tails which average 5.5 inches. When members of the F1 interbreed, the 496 offspring have tails which also average 5.5 inches in length, but vary much more than those of their parents, with the range between 4 and 7 inches. Two members of...
