Answer:

A. Centrosomes

Explanation:

Homologous chromosomes exchange genetic material through crossing over Centrosomes.

ANSWER:

The correct option is C: Chiasma. Homologous chromosomes share genetic information in chiasma during crossing over.

EXPLANATION:

  • Chiasma is basically a point of contact or a physical link between two chromatids. These chromatids belong to homologous chromosomes and any genetic information can be exchanged at this point of contact.
  • This exchange takes place generally during meiosis rather than mitosis. The exchange of genetic information and material via the chiasma brings about chromosomal segregation in a proper manner.
