|
|
Mendel's law of Dominance
|
states that one of the factors for a pair of inherited traits will be dominant and the other recessive, unless both factors are recessive.
|
|
|
Mendel's law of Segregation
|
states that during the formation of reproductive cells (gametes), pairs of hereditary factors (genes) for a specific trait separate so that offspring receive one factor from each parent.
|
|
|
Mendel's law of Independent Assortment
|
that chance determines which factor for a particular trait is inherited
