[The Question]

Hi everyone

I just have problem understanding these terminologies. Could someone please make me clear what "homozygous mutant" and "heterozygous mutant" are?

Thank you in advance

Each diploid cell has two copies of every gene.  Any given gene may contain a mutation.  If only one copy of the gene contains the mutation it is a heterozygous mutant.  If both copies of the gene contain the mutation it is a homozygous mutant.

Thank you Doxorubicin for removing the confusion.
