Answer the following question given this paragraph: 

The Chromosomal Theory of Inheritance was consistent with Mendel’s laws and was supported by the following observations: • During meiosis, homologous chromosome pairs migrate as discrete structures that are independent of other chromosome pairs. • The sorting of chromosomes from each homologous pair into pre-gametes appears to be random. • Each parent synthesizes gametes that contain only half of their chromosomal complement. • Even though male and female gametes (sperm and egg) differ in size and morphology, they have the same number of chromosomes, suggesting equal genetic contributions from each parent. • The gametic chromosomes combine during fertilization to produce offspring with the same chromosome number as their parents.


Q: During meiosis, each parent synthesizes gametes that contain only half of their complement of what?

- receptors

- neutrons

- atoms
