“Y” Did He Have To Ask?

(I go to an all-girls school, and in ninth or tenth grade we come to the topic of genes in our biology class. Our textbook has a picture of the human chromosome pairs. Our teacher is male.)

Teacher: “So, can anyone tell me why this one chromosome is different?”

Student: “Maybe the person is handicapped?”

Teacher: “From your perspective, probably.”

(It was a Y chromosome.)
