Which condition results from a male with the chromosome pattern 2n=47; XXY?

The condition associated with a male having the chromosome pattern 2n=47; XXY is Klinefelter Syndrome. This genetic condition occurs when a male has an extra X chromosome, resulting in a total of 47 chromosomes instead of the typical 46. The presence of the additional X chromosome leads to various physical and developmental characteristics, such as reduced testosterone levels, infertility, and sometimes breast tissue development.

Klinefelter Syndrome is specifically characterized by the XXY genotype, and it is part of a group of conditions known as aneuploidies, which are caused by chromosomal abnormalities. This condition affects males since the presence of the Y chromosome indicates male phenotypic development, regardless of the additional X chromosome.

Other options, such as Turner Syndrome, Triple X Syndrome, and Super Male Syndrome, describe different chromosomal patterns and characteristics. Turner Syndrome is typically characterized by a female having only one X chromosome (45,X), while Triple X Syndrome involves an extra X chromosome in females (47,XXX). Super Male Syndrome, also known as XYY syndrome, involves males having an extra Y chromosome (47,XYY). Each of these conditions has distinct genetic and phenotypic implications, which makes Klinefelter Syndrome unique for the
