9.3 Genetic Diversity and Adaption

Genetic diversity - @@total number of different alleles in a population@@
Population - @@group of individuals that live in the same place and can interbreed@@
Species consists of 1 or more population
Species - @@2 members can interbreed and produce fertile offspring@@
@@The greater the genetic diversity of a species the greater chance of survival in an environment a species has@@
This is due to a wider range of alleles and therefore a @@wider range of characteristics@@

Not all alleles are equally as likely to be passed from 1 generation to another
This is because @@some alleles provide adaptions with a greater advantage so that individual is more likely to survive and then pass them on to the next generation@@
Within any species there is a gene pool with a range of alleles
@@Random mutations of alleles may result in anew allele@@ which is usually harmful
@@Some mutations may prove advantageous for the population@@
The individuals with that allele have a greater advantage and are @@more likely to survive in the environment@@
Those individuals will @@survive and breed more, causing the frequency of the advantageous allele and reducing the frequency of the less advantageous ones@@
