Answer:

They need both if they are producing animal gametes.

Explanation:

  • They need both if they are producing animal gametes.
  • A human bone marrow cell, in prophase of mitosis, contains 46 chromosomes.
  • They are sites at which microtubules attach to chromosomes.

They employ both to produce animal gametes which are egg cells (female gamete) or sperm (male gamete).

Hope that helps!
