| Answer» When traits are passed from one generation to another they follow principles of genetic inheritance that were first defined by Gregor Mendel, a monk and scientist who worked in the mid-nineteenth century. Mendel\'s studies yielded three "laws" of inheritance: the law of dominance, the law of segregation, and the law of independent assortment.The Law of Segregation: A parent may have two distinct alleles for a certain gene, each on one copy of a given chromosome. Mendel\'s second law, the law of segregation, states that these two alleles will be separated from each other during meiosis. Specifically, in the second of the two cell divisions of meiosis the two copies of each chromosome will be separated from each other, causing the two distinct alleles located on those chromosomes to segregate from one another.The Law of Independent Assortment: Mendel\'s third law, the law of independent assortment, states that the way an allele pair gets segregated into two daughter cells during the second division of meiosis has no effect on how any other allele pair gets segregated. In other words, the traits inherited through one gene will be inherited independently of the traits inherited through another gene because the genes reside on different chromosomes that are independently assorted into daughter cells during meiosis. | |
