Why are beneficial traits more likely to be passed onto offspring?
Because they come from recessive alleles.
Because they come from dominant alleles.
Because they are more likely to survive and reproduce.
Because the trait is an acquired phenotype.

Natural selection, finding food
This gecko has an extreme look, which answer best explains how the gecko got this way?
The gecko is being fancy to attract a mate, the more they look like leaves the more attractive they are the more often they mate.
There was variation in the gecko population, geckos that looked more like leaves had camouflage and survived predators more often, living to reproduced more often.
This gecko is a mutant and will likely not survive to pass on its genes because it looks so strange and predators will notice it more now.
There is no gecko... it's all in your mind...
An ecological niche is ...?
a small physical space

selective pressure
mutation
adaptation
fancy trait

Sexual Reproduction
Asexual Reproduction
Budding
Pollination
