Answer:

The given blank can be filled with zygotic mortality.  

Explanation:

An array of mechanisms, physiological procedures, and behaviors, which inhibit two distinct species that mate from generating offspring, or which makes sure that any produced offspring is not fertile. It can be either prezygotic, that is, obstructions that inhibit fertilization or postzygotic, that is, the obstructions, which take place after the formation of zygote.  

A kind of obstruction known as the zygotic mortality in which the sperm and egg come into contact with each other and fuse, however, the zygote dies due to the absence of further development. It is one of the forms of post-zygotic barriers.

unethical.

Explanation:

1) Humans have DNA that is structurally very different from

other mammals.

3) Human genes are made of too many different types of

simple sugars.

4) Some people consider human genetic experiments

unethical.

The statement that provides the most likely reason that a human has not yet been cloned is that some people consider human genetic experiment unethical.

<em>Option 1 is incorrect because human DNA is similar in structure to other living organisms with components such as a phosphate group, a deoxyribose sugar and purine/pyrimidine bases.</em>

<em>Option 2 is incorrect because cloning is not limited to asexually reproducing organisms only. Sheep, for example, produces only sexually and has been successfully been cloned.</em>

<em>Option 3 is incorrect because human genes, just like every other organisms is consist of DNA with deoxyribose pentose sugar being one of the components. The situation of too many different types of simple sugars doe not arise.</em>

The correct option is 4.
