Suppose that a given gene undergoes a mutation to its dominant allele such that two out of 100,000 offspring exhibit the new mutant phenotype. assuming that these offspring are heterozygous, what is the mutation rate for the gene

Suppose:

a given gene undergoes a mutation to its dominant allele such that two out of 100,000 offspring exhibit the new mutant phenotype.

Assuming that these two offspring are heterozygous,

Mutation rate for the gene = 1/100,000
