Which chromosomal pattern is associated with tall stature, infertility, and language difficulties in males?

Explanation:
Having an extra X chromosome in a biologically male produces Klinefelter syndrome. Individuals with this pattern are typically 47,XXY. The extra X chromosome interferes with testicular development, leading to testicular atrophy and infertility due to impaired spermatogenesis. It also often comes with language-based learning difficulties and mild cognitive differences, which aligns with the described language problems. The tall stature is a common feature because epiphyseal closure can be delayed. Other chromosomal patterns don’t fit as well: XYY males can be tall but infertility is not a hallmark; Turner syndrome affects females (46,X) and features short stature and gonadal dysgenesis; Lesch-Nyhan is a metabolic disorder with neurological and behavioral symptoms, not a sex-chromosome pattern.
