Chromosomal Alterations and Their Impact on Phenotype
Errors in mitosis or meiosis can result in changes in phenotype, often due to alterations in chromosome structure such as deletion, duplication, inversion, and translocation. Nondisjunction can lead to abnormal chromosome number, resulting in disorders like aneuploidy. Polyploidy, with extra complet
