Genotype refers to the two ​ (a)   that control the phenotype of a trait

Ex: Eye Color

​ (b)   - Homozygous (same) Dominant brown = 2 brown

​ (c)   - Homozygous (same) recessive blue = 2 blue

​ (d)   - Heterozygous (not same) = 1 brown + 1 blue​

DNA mutations are random ​ (a)   in DNA that lead to a changes in ​ (b)   sequences that code for specific ​ (c)  

*Addition/Insertion = More bases

*Deletion = Fewer bases                         

*Substitution = Same number but different sequence (A, T, C, or G)
