The broadest definition of a pseudogene is any gene that has received inactivating mutations and can no longer make a functional product.
A retropseudogene is a non-functional cDNA copy of a processed RNA that has integrated elsewhere into the genome.
A non-processed pseudogene is an inactive copy of a gene that has arisen by some type of gene duplication.
An estimated 14,000 pseudogenes are found in the human genome.

Shell coiling of the snail Limnaea peregra(genetic maternal effect) the shell coils (s+s+) which is termed dextral coiling, while some snails exhibiting sinistral coiling (ss). The allele for dextral (s +) is dominant over the allele for sinistral (s). If a male homozygous for dextral alleles (s+s+) is crossed with a female homozygous for sinistral alleles (ss) all of the F1 are heterozygous (s+s) and have a sinistral shell. If these F1 snails are self-fertilized, what is the phenotype of the F2 snail?
