Genotype the heritable genic indentity, the set of genes in an organism, cell or individual with reference to your individual traits, it difine the sum of all genes. Genotype together with by its environment influences phenotype.
1) variation in traits.
population of beetles: equal brown and green numbers in population.
2) differential reproduction.
Natural habitat is in trees. Green leaves hide green beetles.
The brown beetles are noticed by birds in the area.
Birds eat brown beetles.
More green beetles survive than brown beetles
3) heredity
Green beetles reproduce in greater numbers than brown beetles
4) end result
Beetle population changes from brown and green to mostly green beetles.
