Genetic recombination is an important process for DNA repairing and increasing genetic variation, thereby enriching the gene pools for the survival and vitality of a species. In eukaryotes, meiosis is a major means for genetic recombination. For genes on non-homologous chromosomes, mixing of paternal and maternal genes is achieved through different chromosome configurations at metaphase I of meiosis...
The G-banding technique is routinely used for generating characteristic banding patterns for chromosome identification and karyotyping. Since G-band patterns are not static, training cytogenetics technologists to master the skills of chromosome analysis is a long process. Furthermore, the opportunities for biology students to access a wide range of different chromosome aberrations for practice are...
Teaching fundamental principles of genetics such as segregation and independent assortment of genes could be challenging for high school and college biology instructors. Students without thorough knowledge in meiosis often end up of frustration and failure in genetics courses. Although all textbooks and laboratory manuals have excellent graphic demonstrations and photographs of meiotic process, students...
Karyotyping is a fundamental step in chromosome analysis. Since G-banding patterns of any chromosomes in the metaphase spread are changeable, it is difficult and time consuming for students to master the technique of karyotyping. Current methods for leaning karyotyping are ineffective, and therefore it is necessary to develop a software program to help students learn the skill efficiently. Virtual...
