Explanation / Answer

The female butterfly has no chance of obtaining the Z allele from mother

because if we cross

ZZ(father) and ZW(mother) to get a daughter

the father being monogametic will contribute Z allele

the mother cannot contribute Z as, two ZZ will make it a son

In the same way the maternal also had ZZ , it did contribute one Z to his daughter but the daughter cannot pass it to her daughter

The father and the maternal grandmother has contribution towards the daughter

the father donated one Z to the daughter as it is ZZ
the paternal grandmother also gives one Z to its son

this Z allele may be passed to the next generation

So, the butterfly has obviously inherited one Z from her father

and might from her paternal grandmother.
