Sperm and Oocyte Chromosomal Abnormalities [PDF]

Biomolecules, 2023
Gametogenesis, the process of producing gametes, differs significantly between oocytes and sperm. Most oocytes have chromosomal aneuploidies, indicating that chromosomal aberrations in miscarried and newborn infants are of oocyte origin. Conversely, most
