What happens if a baby has two Y chromosomes?
If it doesn't have an X, it will not survive.
However, if it does have an x --> XYY:
thanks!!
If a baby has two Y chromosomes, it would have a condition called XYY syndrome, also known as Jacob's syndrome. This condition occurs due to an extra copy of the Y chromosome in males. Typically, males have one X and one Y chromosome (XY), but in the case of XYY syndrome, they have two Y chromosomes (XYY).
XYY syndrome typically does not cause any significant physical abnormalities, and many individuals with this syndrome may not even be aware they have it. However, there may be some behavioral and developmental differences that can vary from person to person. These can include taller stature, delayed motor skills, learning difficulties, speech and language delays, and behavioral issues such as impulsivity or social difficulties. It's important to note that not all individuals with XYY syndrome will experience these characteristics, and the range and severity of symptoms can vary widely.
If you suspect that a baby or child may have XYY syndrome, it is important to consult with a healthcare professional who can perform appropriate genetic testing and provide guidance and support. Genetic testing such as a karyotype analysis, which examines the chromosomes, can confirm the presence of an extra Y chromosome.
