Individual heterozygous

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