9.3 genetic diversity & adaptation Flashcards
1
Q
what is the definition of genetic diversity?
A
total number of different alleles in a population
2
Q
how does an increasing number of alleles affect genetic diversity & adaptation?
A
higher genetic diversity & higher chance individuals will survive environmental changes
3
Q
how could genetic diversity allow natural selection to occur?
A
more alleles leads to more characteristics & higher probability individuals have characteristics best suited to the environment
4
Q
how are new alleles resulted from?
A
random mutations
5
Q
how would allele frequency be affected if an advantageous allele be passed on?
A
increases
