Due to nondisjunction of chromosomes during spermatogenesis, sperms carry both sex chromosomes (22A + XY) and some sperms do not carry any sex chromosome (22A + O). If these sperms fertilise normal eggs (22A + X), what types of genetic disorders appear among the offsprings?

ATurner's syndrome and Klinefelter's syndrome
Correct Answer
BDown's syndrome and Klinefelter's syndrome
CDown's syndrome and Turner's syndrome
DDown's syndrome and cridu-chat syndrome

Solution

A syndrome is a set of medical signs and symptoms that are correlated with each other and, often, with a particular disease or disorder. When diagnosing a condition or disease, doctors tend to look for a group of symptoms existing together. As long as a set of symptoms remains mysterious, it may be referred to as a specific syndrome. Turner syndrome (TS), also known as 45,X or 45,X0, is a condition in which a female is partly or completely missing an X chromosome. Turner syndrome is not usually inherited from a person's parents. Turner syndrome is due to a chromosomal abnormality in which all or part of one of the X chromosomes is missing or altered. While most people have 46 chromosomes, people with TS usually have 45. No cure for Turner syndrome is known. Klinefelter syndrome (KS) also known as 47,XXY or XXY, is the set of symptoms that result from two or more X chromosomes in males. The primary features are infertility and small testicles. Often, symptoms may be subtle and many people do not realize they are affected. Its signs and symptoms vary among affected individuals. In some cases, the features of the condition are so mild that the condition is not diagnosed until puberty or adulthood, and researchers believe that some affected men and boys are never diagnosed.
So the correct option is 'Turner's syndrome and Klinefelter's syndrome'.
