Disorders in chromosome number,...The number, size, shape, and banding pattern of chromosomes make them easily identifiable in a karyogram and allow for the assessment of many chromosomal abnormalities. Disorders in chromosome number, or aneuploidies, are typically lethal to the embryo, although a few trisomic genotypes are viable. Because of X inactivation, aberrations in sex chromosomes typically have milder effects on an individual.

It notes that while transformed cells can form tumors in test subjects despite not being cancerous, normal cells require specific nutrients and maintain a normal karyotype. In contrast, transformed and cancer cells can survive on simpler media and often exhibit abnormal karyotypes with irregular chromosome structures.

Key syndromes like Down Syndrome, Turner Syndrome, and Klinefelter syndrome are discussed, alongside their implications on development and fertility. Cytogenetic techniques like karyotyping help identify these conditions, revealing issues such as aneuploidy and structural rearrangements (e.g., deletions and translocations).
