1 BIO 182: General Biology II Spring Semester 2011 Chapter 13 Mendel and the Gene Cayle Lisenbee UCENT 355 (602) 496-0641 [email protected] Office Hours: Mon/Wed 3:00-5:00 pm, Tue/Thu 12:00-1:00 pm Instructional Aides: Neda Javidan, Alex Gannon, Kristina Flynn Chromosomal Inheritance Chromosomal Inheritance The chromosome theory of inheritance states that a cell’s chromosomes are composed of Mendel’s hereditary determinants, or what we now call genes. The behavior of chromosomes during gamete formation (meiosis) explains Mendel’s principles of inheritance. Principle of segregation: homologous chromosomes with alleles for a gene align and then separate independently during meiosis I. Principle of independent assortment: genes located on different nonhomologous chromosomes assort independently of one another at meiosis I. 1/31/2011 2 BIO 182: General Biology II (Lisenbee)
