7
Q
Genetic diversity def=
A
- DEF= The genetic variety in a species
- Offspring carry new combinations of genes resulting in genetic differences or genetic diversity
- Genetic diversity is critical for adaptation and evolution - variety at the genetic level is the basis of adaptation. If every individual was exactly the same, the whole species could get “wiped out” by the same threat.
