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.
Concept 5 Genetic inheritance follows rules. When Mendel proposed that each trait is determined by a pair of genes, it presented a potential problem. If parents pass on both copies of a gene pair, then offspring would end up with four genes for each trait. Mendel deduced that sex cells â sperm and eggs â contain only one parental gene of each pair. The half-sets of genes contributed by sperm and egg restore a whole set of genes in the offspring. Mendel found that different gene combinations from the parents resulted in specific ratios of dominant-to-recessive traits.
