Solution
The question seems to be based on the principles of Mendelian genetics, but it's missing some crucial information. In Mendelian genetics, traits are determined by pairs of 'alleles' (versions of a gene). Each parent contributes one allele to the offspring.
However, in your question, it's not clear what the relationship is between the yellow (Y), blue (B), and green (BY) flowers. If we assume that green is a combination of blue and yellow (as suggested by the 'BY'), then we might guess that 'B' and 'Y' are the two alleles, and that blue and yellow are 'dominant' traits (meaning you only need one 'B' or 'Y' allele to have a blue or yellow flower), while green is a 'recessive' trait (meaning you need both a 'B' and a 'Y' allele to have a green flower).
If that's the case, then a green flower must have one 'B' and one 'Y' allele (since it needs both to be green), while a blue flower could either have two 'B' alleles, or one 'B' and one 'Y'. Without knowing which is the case, it's impossible to predict the colors of the offspring.
If we knew more about the genetics of poofkins, we could use a Punnett square to predict the probabilities of each color in the offspring. But without that information, we can't provide a definitive answer.
