what does being born with an extra y chromosome mean
XYY syndrome XYY syndrome is a genetic condition in which a male has an extra Y chromosome.[1] Symptoms are usually few.[3] They may include being taller than average, acne, and an increased risk of learning problems.[1][3] The person is generally otherwise normal, including normal fertility.[1]
Millennials Millennials (also known as Generation Y) are the generational demographic cohort following Generation X. There are no precise dates for when this cohort starts or ends; demographers and researchers typically use the early 1980s as starting birth years and the mid-1990s to early 2000s as ending birth years. Millennials are sometimes referred to as "echo boomers" due to a major surge in birth rates in the 1980s and 1990s, and because millennials are often the children of the baby boomers. The 20th-century trend toward smaller families in developed countries continued, however, so the relative impact of the "baby boom echo" was generally less pronounced than the post–World War II baby boom.
