A two-step division reducing the chromosome number by half to produce haploid gametes, introducing genetic variation via crossing over . 3. Chromosomal Variations
DNA is transcribed into RNA, which is then translated into proteins. Principles of Genetics and Cytogenetics
Deletions, duplications, inversions, and translocations (where segments of chromosomes break and reattach elsewhere). 4. Molecular Foundations A two-step division reducing the chromosome number by
