|
Genotype
|
Specific constitution of an individual- when you know both genes you know the genotype
|
|
|
Phenotype
|
The genetically controlled observable traits of an individual- Traits you can see
|
|
|
Dominant Trait
|
Shows phenotypically when paired with a recessive trait. A capital letter is used for dominant trait
|
|
|
Recessive Trait
|
In order to be observed it mist not be paired with a dominant trait. Small letter is always used to represent it.
|
|
|
Homozygous
|
Having identical alleles for one or more genes. ie HH or hh
|
|
|
Heterozygous
|
Having different genes for a given trait. ie Hh
One for each trait |
|
|
Allele
|
One of the alternate forms of a gene usually distinguished from other alleles by its phenotypic effects
|
|
|
Traits
|
Many traits have 2 genes. One from each parent that determine traits.
|

|
Gregor Mendel
|
Father of genetics
