Given that all puppies are black, it suggests the black poodle is likely homozygous dominant (BB) for black fur. If it were heterozygous (Bb), some white puppies (bb) could be expected due to the white poodle being homozygous recessive (bb). However, without genetic testing, we cannot be absolutely certain, hence "probably" rather than "definitely."
