X-linked Traits01:19

X-linked Traits

45.6K
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.

Sex-linked Disorders01:43

Sex-linked Disorders

94.2K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

X and Y Chromosomes

16.5K
Among mammals, the gender of an organism is determined by the sex chromosomes. Humans have two sex chromosomes, X and Y. Every human diploid cell has 22 pairs of autosomes and one pair of sex chromosomes. A human female has two X chromosomes, while a male has one X chromosome and one Y chromosome.
The germline cells such as egg and sperm cells carry only half the number of chromosomes, i.e., 22 autosomes and one sex chromosome. All eggs have an X chromosome, while sperm cells can carry an X or...

Lenz's Law01:15

Lenz's Law

5.8K
The direction in which the induced emf drives the current around a wire loop can be found through the negative sign. However, it is usually easier to determine this direction with Lenz's law, named in honor of its discoverer, Heinrich Lenz (1804–1865). Lenz's law states that the direction of the induced emf drives the current around a wire loop always to oppose the change in magnetic flux that causes the emf.
If a bar magnet is moved toward a coil such that the magnetic flux...

Lateralization01:28

Lateralization

1.3K
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Summary
This summary is machine-generated.

Surveys indicate fewer than 1% of Chinese students are left-handed, significantly lower than the global average. Cultural factors and historical practices likely contribute to this low prevalence of left-handedness in China.

Area of Science:

  • Human laterality
  • Cultural anthropology
  • Sociology

Background:

  • Global prevalence of left-handedness is estimated between 10-12%.
  • Surveys in China since the 1980s report less than 1% left-handedness among students.
  • This discrepancy prompts an investigation into the reasons behind low left-handedness rates in China.

Purpose of the Study:

  • To explore the reasons for the low reported prevalence of left-handedness in China.
  • To examine the interplay of cultural, historical, and biological factors influencing attitudes toward left-handedness.
  • To understand the societal pressures and discrimination faced by left-handed individuals globally.

Main Methods:

  • Review of historical and cultural factors influencing attitudes toward left-handedness in China.
  • Comparative analysis of practices in other societies, including North and East Africa.
  • Synthesis of traditional values and practical considerations shaping left-handedness prevalence.

Main Results:

  • Chinese attitudes and practices toward left-handedness are shaped by a combination of factors.
  • Historical and cultural experiences, including traditional values and practical considerations, have merged to reduce left-handedness.
  • Similar practices of attempting to 'cure' left-handedness exist in other cultures, often reinforced by religion.

Conclusions:

  • The low prevalence of left-handedness in China is likely due to a convergence of cultural and historical forces.
  • Attitudes and practices toward left-handedness are over-determined, transcending specific cultures while responding to unique pressures.
  • Left-handedness is associated with discrimination and stigma for a significant portion of the global population, including China, India, and the Islamic world.
