Turner syndrome occurs in females who instead of having two X chromosomes have either only one X chromosome or a fragmented X chromosome. Klinefelter syndrome occurs in males who have multiple X chromosomes. Consider the karyotype

The karyotype for Klinefelter Syndrome is XXY.

Explanation:

Klinefelter syndrome is a rare genetically inherited disease where an individual acquires two X chromosomes and one Y chromosome. Due to this, this individual will have mixed male and female characteristics.  

This happens when there is a nondisjunction of homologous chromosomes where they fail to separate during nuclear division resulting in abnormal chromosomal division in the daughter nuclei.

The pairing of a sperm or egg with an extra X chromosome with a normal egg or sperm respectively results in the individual gaining three sex chromosomes instead of two as in normal individuals.

Klinefelter syndrome is characterized by low testosterone hormone levels, testes that are not fully developed, body and facial hair during puberty, belly fat and wide hips, long arms and legs etc along with such males not able to produce sperms.  

Testosterone hormone replacement therapy can be done to correct this syndrome.

This disease can be diagnosed by karyotype analysis of blood sample of the patient or even from amniotic fluid surrounding the fetus during pregnancy.

Turner syndrome is a genetic disorder occuring due to chromosomal monosomy.

do yall know the answer?
