  • After further study, turkeys, like all birdscitation needed, have ZW sex chromosomes, ZZ being male and ZW female.

    A parthenote egg starts by duplicating its haploid genome to become diploid. A W chromosome becomes WW, which is inviable and results in termination. So only males (ZZ) turkeys can be hatched from parthenogenesis, and they are technically not clones of the mother (but share a all of the DNA in one form or another).

    There’s a high mortality rate of parthenotes, and they seem to have on average slower growth, smaller adult size, and reduced fertility. But they are otherwise indistinguishable from regular males.
