Self-proclaimed monarchy: A form of government where the monarch claims a monarch title without a nexus to the previous monarch dynasty.
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
Complete trisomy (having three copies of the entire chromosome) is lethal within days after conception. [13] Some partial deletions and partial duplications produce birth defects. The following diseases are some of those related to genes on chromosome 1 (which contains the most known genetic diseases of any human chromosome):
The cause of hydranencephaly is not clear. Hydranencephaly is a result of an injury of the nervous system or an abnormal development of the nervous system. The neural tube closes in the sixth week of the pregnancy, [15] so hydranencephaly develops during these weeks of the pregnancy. The cause of these injuries/development is not clear. [16]
A first-order system is hyperbolic at a point if there is a spacelike surface S with normal ξ at that point. This means that, given any non-trivial vector η orthogonal to ξ, and a scalar multiplier λ, the equation Q(λξ + η) = 0 has m real roots λ 1, λ 2, …, λ m. The system is strictly hyperbolic if these roots are
The first parliaments date back to Europe in the Middle Ages. The earliest example of a parliament is disputed, especially depending how the term is defined. For example, the Icelandic Althing consisting of prominent individuals among the free landowners of the various districts of the Icelandic Commonwealth first gathered around the year 930 (it conducted its business orally, with no written ...
Klinefelter syndrome (KS), also known as 47,XXY, is a chromosome anomaly where a male has an extra X chromosome. [10] These complications commonly include infertility and small, poorly functioning testicles (if present).
In genetics, chromosome translocation is a phenomenon that results in unusual rearrangement of chromosomes. This includes balanced and unbalanced translocation, with two main types: reciprocal, and Robertsonian translocation. Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous chromosomes
