Individuals with 49,XXXXY syndrome have 49 chromosomes.
Understanding 49,XXXXY Syndrome
49,XXXXY syndrome is a rare chromosomal condition affecting males. It's characterized by the presence of three extra X chromosomes and one Y chromosome (49,XXXXY karyotype), resulting in a total of 49 chromosomes in each cell. This extra genetic material leads to a range of developmental and physical challenges.
Key Characteristics of 49,XXXXY Syndrome:
- Intellectual disability: Individuals with 49,XXXXY syndrome often experience intellectual delays and disabilities.
- Developmental delays: Developmental milestones may be reached later than average.
- Physical differences: Physical characteristics can vary, but may include ambiguous genitalia, hypotonia (low muscle tone), and other features.
- Rarity: This syndrome is extremely rare, occurring in approximately 1 out of 85,000 to 100,000 male births.

It's important to note that while F1 hybrids of swamp and river buffalo can also have 49 chromosomes, the question's context points towards human genetics. Therefore, the primary answer focuses on the human condition of 49,XXXXY syndrome.
