An individual is heterozygous, one copy of the gene has a mutation in exon 1 and
the other copy of the gene has a mutation exon 3. Draw their genes, with
mutations. What RNA molecules can be expressed from these alleles? Will this
heterozygote have a mutant or a wild-type phenotype? Explain. Assume the 1/3
variant and the 1/2/3 variant are required in different tissues.
