Lesson details
Lesson outcome
I can explain how the genotype affects the phenotype of an organism.
Show transcript
An individual inherits two copies of each gene in a pair of chromosomes.
Versions of genes are called alleles, they can be recessive or dominant, indicated with a capital or lowercase letter.
The combination of alleles that an organism has is called its genotype.
Different alleles of a gene are associated with different versions of the same characteristic called the phenotype.
Some phenotypes are determined only by genotype, others are also affected by the environment.
