Variation
INTERspecific variation = differences between different species (like internet - worldwide)
INTRAspecific variation = differences between the same species (like intranet - small group)
Interspecific Variation
- Differences mainly due to DNA differences
- Differences between species arise due to: the structure and sequence of genes in each organism and the way in which genes are expressed
- A gene csn only have an impact on an organism if it is switched on and used to make a particular protein.
Intraspecific Variation
- The genotype of an organism is the genetic make-up, the collection of alleles tat the organism has inherited from its parents. (one allele from each parent for each gene)
- The phenotype of an organism of an organism is the collection of obsrvable features that it has e.g. colour of hair
- Genotype + environment = phenotype
