A researcher raises a sample of unrelated macaque monkeys in identical laboratory environments. He finds significant differences among these monkeys in their preference for novel visual stimuli. What might the researcher legitimately conclude concerning the relative effects of nature and nurture on the preference for visual novelty?

nature contributes substantially to the monkey's preference for visual novelty

Explanation:

In a nature versus nurture research, the researchers aims at studying the effect of genetics (nature) versus environment (nurture) on a particular behavior of the subjects. Nature asserts that the behavior and preferences of a subject is majorly determined by genetic make-up while nurture asserts that the behavior and preferences of a subject is determined by the environment which he grew in.

In study of monkeys kept under similar conditions showing different preferences, can only be explained that the environment which is homogeneous in this case did not play affect their behaviors and preferences but that genetics plays a more substantial role in their preferences  

the answer is "meiosis ii in the mother".

the procedure of meiosis includes two divisions of the hereditary material. the main division is known as the decrease division – or meiosis i – on the grounds that it lessens the quantity of chromosomes from 46 chromosomes or 2n to 23 chromosomes or (n depicts a solitary chromosome set). in people, the decrease division results in two sperm cells each with 23 chromosomes or an egg cell with 23 chromosomes and one disposed of polar body. the second division – or meiosis ii – is called equational division. the two sperm cells split again creating four sperm cells, each with 23 or n chromosomes. in oogenesis, the egg cell and polar body partition to shape the ovum and two extra polar bodies. along these lines, the posterity are guaranteed to get one portion of the chromosomes from the mother and one half from the dad.
