The treatment slaves received depended on . the slave code for the region
the slave code for the agricultural product
the personality and character of the slave owner
the number of slaves and how long the owner had owned them

the personality and character of the slave owner.

Explanation:

During the slavery period, the treatment of slaves were based on the personality and character of the owner and not the slave codes. The slaves during this period were abhorred and excluded from enjoying any civil rights. They were regarded as disgust and contempt. They did not have right to marry, to learn and write, etc.

But the slaves were free from these codes under those owner who had good nature. Such owners would help their slaves to learn to read and write. Example of such owner can be found in the life of Frederick Douglass, who was taught alpabets by his owner's wife, Sophia.

Thus the correct answer is option third.

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
