1. a future offspring has just been conceived. when does it have the highest level of potency?

a. pluripotency

b. totipotency

c. unipotency

d. multipotency

When a future offspring has just been conceived it has the highest level of potency in Totipotency.

Explanation:

Potency is the ability of cells to differentiate. AT different stages of development the level of potency changes. The highest level of potency is Totipotency and these cells have the ability to develop a whole organism. The common examples are spores and zygote. In embryonic stage the cells are Pluripotent and they can differentiate into different type of cells. Pluripotent cells after further development changes into Multipotent cells. Unipotent cells have the least potency and can develop only in one cell linage.
