A study of X chromosome linkage with field dependence and spatial visualization
Behavior Genetics
|September 1, 1977
Summary
Brothers with identical Xg(a) blood group phenotypes show greater similarity in field dependence cognitive style. This suggests a potential X-linked gene influencing this trait, requiring further validation.
Area of Science:
- Behavioral genetics
- Human genetics
- Cognitive neuroscience
Background:
- The X chromosome plays a role in various human traits.
- Understanding the genetic basis of cognitive styles is crucial.
Purpose of the Study:
- To design and apply a study investigating X-chromosome linkage.
- To explore the genetic underpinnings of cognitive styles, specifically field dependence.
- To propose a linkage hypothesis based on observed data.
Main Methods:
- Examined 67 three-son families.
- Assessed X chromosome markers: red-green color vision and Xg(a) blood groups.
- Administered cognitive tests measuring field dependence and spatial visualization.
Main Results:
- Identical Xg(a) phenotype brothers exhibited more similar field dependence scores than dissimilar brothers.
- This finding was tentative due to limited sample size and numerous linkage analyses.
Conclusions:
- The results tentatively support the hypothesis of an X-linked gene influencing field dependence.
- Further cross-validation is necessary to confirm the proposed linkage between Xg(a) phenotype and field dependence.

Karyotyping
Describing the number and physical features of chromosomes can reveal abnormalities that underlie genetic diseases. This description is facilitated by special staining techniques that produce a particular banding pattern on each chromosome. State-of-the-art techniques make this approach even more powerful, enabling the detection of individual genes that cause disease.A Simple Chromosome Staining Technique Provides Valuable Scientific InsightSome genetic diseases can be detected by looking at...
X-linked Traits
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”.
X and Y Chromosomes
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...

The Ratio of X Chromosome to Autosomes
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female Drosophila...

Genome-wide Association Studies-GWAS
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
