Cytogenetics

During the middle of the 20th century, corn cytogenetics dominated the biological sciences, due in large part to Barbara McClintock's efforts. Cytogenetics is the study of chromosome behavior and structure from a genetic point of view. This includes chromosome movement during meiosis and mitosis, chromosome pairing during meiosis, and chromosomal variation due to changes in chromosome structure and number. Chapters 3 and 12 discuss chromosome behavior during mitosis and meiosis, respectively. Therefore, this section will emphasize changes in chromosome structure and number. These changes occur at low frequency, but since their effects are often large, they can have a dramatic influence on the evolutionary success of populations or species.
