Answer:
Dominant
Explanation:
In the top row of the pedigree, there is an affected heterozygous male, and an unaffected homozygous female. Of their children, 2 are affected (a male and a female) and 2 are unaffected (a male and a female). The unaffected individuals are both homozygous for the w allele, and the affected individuals are both heterozygous, possessing a copy of the W allele from their father. Because it affects males and females, and only one copy of an allele is required to show the green trait, the green allele is dominant.
