b. Homologous chromosomes are always identical, and always control the same trait.
c. Synapsis refers to the process where chromosomes associate to form homologous pairs.

Thanks to anyone who will answer these. 🙂 I have most of them narrowed down but I can’t figure em out by any means /:

There is a secret force run by the government. Only the police, FBI and army know about.
Though it’s no normal secret force. All the agents were born with an extra chromosome,
making them be more, strong, fast and improver their stamina and agility to the max – Though they are nothing like supernaturals.
They protect the world and the artifacts . . . having no limits, they are aloud to kill and torture their criminals and suspects.
Sixteen year old Kyra has been an agent since she was twelve. Being the best in the business, all the criminals are afraid of her, afraid of being tortured by her. One even goes so far to hire a assassin to kill her after what she had done to him. But when Kyra falls for the man who is destined to kill her, she may not survive.
