How do genetic modification variations likely to differ from genetic sexual reproduction variations
ololo11 [35]

Answer:

The  genetic modification variations result in the change in the genome of the organism. In this case, the variations result in expression of a trait in different form than usual. These variations results in genetic mutation, which can be inherited from one generation to another.

In sexual reproduction, the genome of the organism is not altered. In this only an exchange between the maternal and the maternal alleles takes place, these changes does not result in mutations.

You’re welcome :)

Soloha48 [4]

Answer:

Herbivore that feeds on producers

Herbivore that feeds on producers  - this is correct

Herbivore that feeds on primary consumers  - primary consumers are animals and herbivores do not eat animals
