|
alleles
|
different version of the same trait

|
|
genes
|
factor that is passed from parent to offspring

|
hybrids
|
crosses between different parents with different traits
|
|

recessive
|
will exhibit that particular trait when the dominant allele is not present
|

when a trait has 2 different alleles
|
|

when a trait has 2 of the same alleles
