Gregor Mendel's law of independent assortment states that when genes are inherited, they are inherited independent of each other. Linked genes are exceptions to the law of independent assortment because two genes are located on the same chromosome, but this is generally mitigated when chromosomes cross over. law independent assortment Mendel genetics genes chromosomes meiosis crossing over. One of the basic principles of inheritance or genetics is the law of independent assortment otherwise known as Mendel's second law.
As Mendel stated in his Law of Segregation, each organism has two genes for each trait. The different forms of a gene are called alleles. If both alleles are are identical, the organism is said to be homozygous for that trait.For instance, Mendel's purebred tall plants possessed two tall alleles and are said to be homozygous tall.f the two alleles are different, the plant is said to be a hybrid or heterozygous for that trait. As Mendel noted, when both alleles are present, one allele masks or hides the other.
