Answer 1

Answer:

a. sex chromsomes aneuploidy (both trisomy and monosomy) is more common than autosomal aneuploidy

Explanation:

Autosomal aneuploidy conditions occur less frequently than sex chromosome aneuploidies, but include trisomy 21 (Down syndrome), the most well-recognized chromosomal aneuploidy. Other autosomal trisomies discussed include trisomy 13 (Patau syndrome) and trisomy 18 (Edward syndrome). Sex chromosome aneuploidy conditions are more common, occurring in approximately 1 in 400 children, and include Klinefelter syndrome (47,XXY), 47,XYY, trisomy X, Turner syndrome (45,X), and a variety of rarer tetrasomy and pentasomy combinations
