Inheritance Patterns - 6 Chromosomes and Mendel's Laws Chromosomes and Inheritance We briefly mentioned the work of Sutton and Boveri who determined that Mendel's principles of inheritance applied to the behavior of homologous chromosomes during meiosis. But the inheritance patterns discussed to date have involved genes located on different chromosomes, so they have followed Mendel's Principle of Independent Assortment. Each homologous chromosome pair assorts independently, not specific genes. Two genes that are located on the same chromosome will be inherited together, and not assort independently during meiosis.

Unformatted text preview: and Gene Linkage Soon after Sutton and Boveri's connected the behavior of chromosomes to Mendel's pattern of inheritance, it was important to change how we thought about Mendel's conclusions about independent assortment of genes. Although genes that are on different chromosomes indeed assort independently in meiosis, we know that each chromosome contains hundreds of genes and entire chromosomes, not individual genes, are transmitted by meiosis to the gametes. All of the genes located on one chromosome are inherited together we inherit the whole chromosome not each gene. This is known as gene linkage....
