Recent research into mutation involved finding the base
sequence of all genes in parents
and their offspring. It showed that
there was one base mutation per
1.2 × 10^8
bases. Calculate how
many new alleles a child is likely
to have as a result of mutations
in their parents. Assume that
there are 25,000 human genes
and these genes are 2,000 bases
long on average.
