Describe at least five ways two population of the same species could differ

The differences between the two groups of the same species may be influenced by their genetic differences (such as allelic frequencies) and their environment

Individuals of the same species may differ in the following characteristics;

Fertility – on the population may a higher frequency of recessive alleles that reduces their rate of reproductionMetabolism – this also may be determined by the type of allelePhysical appearance – the influence of the environment  in which the population habits on the genotypes of the populationBehavior – this is mostly determined by the environment.  Learning - this is also determined by the environment
