Task: Answer Verification
Input (English): Question: Is boule present in fish and bisexually expressed in adult and embryonic germ cells of medaka?
Answer: The identification of fish boule and dazl genes provides direct evidence for the early gene duplication during vertebrate evolution. Our finding that Obol exhibits bisexual expression in both embryonic and adult germ cells considerably extends the diversity of boule expression patterns and offers a new insight into the evolutions of DAZ family members, expression patterns and functions in animal fertility.
Output (English): yes
