Which is not a cost for organisms that sexually reproduce?
Alekssandra [29.7K]

Answer:

Identical shape and structure.

Those organisms that reproduce sexually have high variations and differences between the parent and its offspring. They are not identical to each other because the offspring gains half characteristics from male parent and half from the female parent making it different from its parent. Identical feature is present in the organisms that reproduce through asexually means from only one parent so the identical shape and structure is not the cost of sexual reproduction.
