To express a recessive phenotype, the genotype must be homozygous (both genes must be recessive) for that recessive trait.

As for examples, I searched Google under the key words "recessive genes" to get these possible sources:

http://en.wikipedia.org/wiki/Recessive_allele
http://www.blinn.edu/socialscience/LDThomas/feldman/handouts/0203hand.htm

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
