Hie dear!
➡️Monosomy is usually lethal because of errors in meiosis result in gametes with abnormal numbers of chromosomes and production, after fertilization, of an aneuploid conceptus.✔️
➡️The genetic imbalance resulting from the loss of an entire chromosome in individuals with deletion-type aneuploidy is generally lethal, except for the full X chromosome monosomy.✔️
Hope it helps you (:
