Answer:
All offspring will have the Bb genotype and therefore, all will have the boring phenotype.
Explanation:
As both the female and the male are true-breeding individuals, we can say that both are hom0zygous beings, that is, they have the same type of allele for this characteristic. Thus, if the femia is borin, it has the "BB" alleles; if the male is busy, he has the "bb" alleles.
That way we can project the offspring alleles between these two individuals through the punnet square shown in the figure attached below. As you can see the entire offspring have the "Bb" alleles and therefore have the phenotype of the dominant allele, the "B".
