Unformatted text preview: e cells. Hertwig, Strasburger, and Flemming suggested that the chromosomes were the carriers of the genetic material. The combination of these ideas into the chromosome theory of inheritance was provided by Boveri and Sutton. The chromosome theory of inheritance relates the behavior of chromosomes to the Mendelian inheritance of traits (Figures 3.16 and 3.17). The principles of this theory are: Mendelʼs law of s egregation can be explained by the s egregation of homologous c hromosomes during meiosis. Mendelʼs law of independent assortment c an be explained by the random allignment of bivalents during metaphase of meiosis I. Chromosomes contain the genetic material. Chromosomes are replicated and passed on from generation to generation. The nuclei of most eukaryotic cells are diploid. During the formation of haploid cells the chromosomes segregate independently. One set of chromosomes is inherited from the father, the other set from the mother. Figure 3.17 demonstrates the relationship between the chromosomal theory of inheritance and Mendel’s studies of independe...
