tinkering with animal cells

[...:)mm]

hi,
i have homework which i have some trouble with. the topic is tinkering with cells and i must do research on 2 questions and research them. but i have been searching for about 2 hours and i cannot find anything. here are the two questions:
1.) What is the result if sperm from one species is used to fertilize an egg from another species?
2.) How can genetic information be transferred from one organism to another?

I have some answers in my text book but i cannot use any information from the textbook. I googled it and i did not find any useful information.
and the topic is about animal cells and not human.
please post any links which would be helpful.
thanks in advance

1. Lookup mules, ligers and tigons. Then look up reproductive barriers.

2. Lookup horizontal gene transfer
