bb

Explanation:

Allele B codes for blue colour.

Allele b codes for green colour.

A gene is usually denoted by two alleles and allele B is dominant over allele b. This means that when B and b are together as Bb, blue colouration will be expressed while green colouration will be repressed.

Hence, for the green colouration to be expressed, B must not be present. The genotype therefore must be bb.
