Genetic diversity is important to allow a species to adapt to changing conditions
What happens to genetic diversity if one population dies out?
If one population dies out, its alleles will be lost from the species and the species will have lost genetic diversity
What is species diversity?
Species diversity is the species richness and relative abundance in an ecosystem
What is species richness?
Species richness is the number of different species in an ecosystem
What is relative abundance?
Relative abundance is the proportion of each species in an ecosystem
What does a dominant species lower?
