Answer:

The answer is mitotic nondisjunction of X Chromosomes.

Explanation:

Nondisjunction is a type of error that occurs resulting in daughter cells with chromosome numbers that are abnormal (aneuploidy). Due to the error in chromosome numbers, it gives rise to conditions such as Down Syndrome (Trisomy 21) and Turner Syndrome (Monosomy X). Nondisjunction can be caused by;

1. Failure of separation to occur in a pair of homologous chromosome during meiosis I.

2. Failure of separation between sister chromatids in Meiosis II.

3. Failure of separation between sisters chromatids in mitosis.

This gives the 45,X in Turner syndrome. The other X chromosome is partly or completely missing. Hence, the female is born with only one X chromosome.

JulsSmile [24]

.The social theory of authors like Karl Marx, Émile Durkheim, Talcott Parsons and Jürgen Habermas proposed different explanations of what the social order is and what is its real basis. For Marx It is the economic structure (level of development of the means of production and production relations specific to a mode of production) which is at the base of a social order. For Durkheim is the set of shared social norms. For Parsons It is the set of social institutions that regulate the structure of orientations for action,  which in turn is based on the structure of cultural values. For Habermas It is the whole of all the above, to which the communicative action adds up.


.The river Huang is considered in China as "the Mother River" by its influence on the development of the Chinese population and culture. It is believed to be the river that allowed the growth of China's population. The Huanghe crosses the whole country, with an influx of immense water, we can say that the river Huang has been fundamental for the history of China and the development of its civilization. In addition, the sandy influx of the river Huang continues to create land by flowing into the sea of Bohai in Shandong province, increasing the surface of arable land year after year.  

Thousands of years ago, China's population and economy was based on agriculture and fishing to survive. The areas covered by the river Huang were then the most fertile and the most appropriate for life. Since antiquity, the river Huang has always marked the political and economic center of China. It was in its surroundings where the most powerful towns or cities were founded. Thanks to its waters, neighboring societies could feed their cattle, irrigate their crops and have an infinite supply of water.  

The Huanghe River or Yellow River was the origin of what we know today as the civilization of the Huanghe River, which has its origins in the Qin and Han dynasties (period from 221 BC to 220 A.D.). For more than a thousand years, the civilization of the Yellow River gave rise to some of the most important inventions in history, such as gunpowder, Chinese Traditional medicine, martial arts, silk, paper, printing, among others. All these Chinese traditions that today are famous all over the world had their origin and their birth thanks to the waters of the river Huang.

.Yes, the Han dynasty reflect confusian values .During the Han Dynasty, their kings adopted the teachings of the Great philosophers of antiquity, Lao-Tse and Confucius. The Government developed well, achieving territorial expansion. Education and writing were promoted in the newly invented rice paper. A great exchange of merchandise was promoted along the Silk Road, which goes from the Pacific Ocean to Persia and India. China officially became a Confucian state and prospered domestically: agriculture, handmade products and trade flourished, and the population reached 50 million.
