Answer:

50%

Explanation:

        Z        O

z    Zz        zo

z    Zz        zo

The males will have two copies of the alleles of the genes present on the Z chromosomes. As females have only one Z chromosome, they will have only one allele for the genes present on the Z chromosome.

The results from the punnet square show that there will be chance that the females of the F2 progeny will have curved-beaks.
