Wrong, sorry. The sperm DOES carry mtDNA into the egg, but it's diluted
out 10,000 fold by the maternal contribution. Check out
http://numbat.murdoch.edu.au/spermatology/sath01.html. The mtDNA has
about 16K base pairs encoding for a limited subset of the oxidative
phosphorylation pathway proteins. Deletions/mutations account for
maternally inherited mitochondrial diseases.

This is a common error in modern Anthropology text books - seems to have
been started by HG Wells about 50 years ago.
