A lot of dominant traits
-
A lot of recessive traits
-
Genetic variation
-
Different climates
Correct Answer
A. Genetic variation -
- 7.
If a group of organisms were all very genetically similar, would they be more likely to become extinct than if they had a lot of genetic variation?
-
No, because their similar genes would help them survive
-
No, because they might have good adaptations
-
Yes, because if they all have the same genes, they wouldn't have any different adaptations that would help in a changing environment or if there was a sickness
