Textbook Question
Chapter 10, Problem 13TYU
In questions 13 and 14, decide whether each is an example of sexual or asexual reproduction, and state why.
13. A diploid queen honeybee produces haploid eggs by meiosis. Some of these eggs are never fertilized and develop into haploid male honeybees (drones).
