Mendel's laws

/ (ˈmɛndəlz) /

pl n

the principles of heredity proposed by Gregor Mendel. The Law of Segregation states that each hereditary character is determined by a pair of units in the reproductive cells: the pairs separate during meiosis so that each gamete carries only one unit of each pair. The Law of Independent Assortment states that the separation of the units of each pair is not influenced by that of any other pair

Science definitions for mendel's laws

Mendel's law

[ mĕndlz ]

Any of the principles first proposed by Gregor Mendel to describe the inheritance of traits passed from one generation to the next.♦ Mendel's first law (also called the 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 second law (also called the law of independent assortment) states that chance determines which factor for a particular trait is inherited.♦ Mendel's third law (also called the 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.
