Definition Meiosis is a special form of nuclear division and is also called maturity division. It contains two divisions, which turns a diploid mother cell into four haploid daughter cells. These daughter cells each contain a 1-chromatide chromosome and are not identical. These daughter cells are needed for sexual reproduction. Introduction In men, the germ … Meiosis
What is the difference to mitosis? Meiosis is very similar to mitosis in terms of the second meiotic division, but there are some differences between the two nuclear divisions. The result of the meiosis are germ cells with a simple set of chromosomes, which are suitable for sexual reproduction. In mitosis, identical daughter cells with … What is the difference to mitosis? | Meiosis
How does trisomy 21 occur? Trisomy 21 is a disease caused by the triple presence of the 21st chromosome. In healthy cells the chromosomes are duplicated, so that the human being has a total of 46 chromosomes. A patient with trisomy 21 has 47 chromosomes and suffers from Down syndrome. The triple presence of the … How does trisomy 21 occur? | Meiosis
What is Klinefelter syndrome? The Klinefelter syndrome occurs in about every 750th man. It is one of the most common congenital chromosomal diseases in which affected men have one sex chromosome too many. They usually have the karyotype 47XXY instead of the usual 46XY. The double X in the chromosome set leads to a testosterone … Klinefelter syndrome
How to treat Klinefelter syndrome Klinefelter’s syndrome cannot be treated from its cause. The disorder during meiosis can therefore not be reversed. However, since most of the symptoms of Klinefelter’s syndrome are caused by low testosterone levels, the therapy consists in supplying testosterone from the outside. This is also known as testosterone substitution. Depending on … How to treat Klinefelter syndrome | Klinefelter syndrome

Prognosis Unfortunately, the prognosis for trisomy 18 is very poor. About 90% of the affected fetuses die in the womb during pregnancy and are not born alive. Unfortunately, the mortality of the born babies is also extremely high. On average, only about 5% of affected infants reach an age of more than 12 months. On … Prognosis | Trisomy 18
Definition Trisomy 18, also known as Edwards syndrome, is a serious genetic mutation. In this case, chromosome 18 occurs three times instead of the usual two times in the body cells. After trisomy 21, also called Down syndrome, trisomy 18 is the second most common: on average, about 1 in 6000 births is affected. Edwards … Trisomy 18
These are the symptoms I recognize as trisomy 18 Edwards syndrome is characterized by a complex of multiple malformations and disabilities. These can be of varying degrees and do not necessarily all occur in every affected infant. Typical is a so-called flexion contracture of the fingers: the fingers are bent and are held in a … These are the symptoms I recognize as trisomy 18 | Trisomy 18
Definition – What is a Wolf-Hirschhorn Syndrome? The Wolf-Hirschhorn syndrome describes a complex of different malformations, which are caused by a change in the chromosomes (chromosomal aberration). The malformations include above all changes in the head, brain and heart. The Wolf-Hirschhorn syndrome occurs in about 1:50. 000 children. It affects girls more frequently than boys … Wolf-Hirschhorn Syndrome
