Stereotypes, Prejudice, and Discrimination

90.3K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Inheritance

Gregor Mendel's pioneering work on the principles of inheritance fundamentally transformed our understanding of how traits are transmitted from generation to generation. His experiments with pea plants laid the groundwork for the discovery of genes, discrete units within organisms that control heredity.
Each gene exists in pairs, and the combination of these genes from both parents forms an individual's genotype. This genotype is a blueprint of potential traits. Examples of genotype...

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Inheritance of Chromatin Structures

6.3K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

Chromosomal Theory of Inheritance

In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”

Summary
This summary is machine-generated.

Transgenerational epigenetic inheritance research shows that ancestral trauma and adversity can impact future generations' health. Evidence suggests these effects can be mitigated through interventions and systemic changes.

Area of Science:

  • Epigenetics and developmental biology
  • Psychiatry and public health

Background:

  • Personal trauma and adversity negatively impact mental and physical health.
  • Emerging research explores transgenerational epigenetic inheritance, where parental exposures affect offspring health.
  • This field investigates how environmental factors influence gene expression across generations.

Purpose of the Study:

  • To review emerging research on transgenerational epigenetic inheritance.
  • To examine how negative exposures in one generation affect future generations' health and well-being.
  • To explore factors that may mitigate these inherited effects.

Main Methods:

  • Review of key concepts in transgenerational epigenetic inheritance research.
  • Analysis of select animal and human studies.
  • Examination of epigenetic mechanisms in transmitting impacts of ancestral stress, trauma, nutrition, and toxicants.

Main Results:

  • Animal studies provide strong evidence for epigenetic transmission of ancestral adversity impacts.
  • Animal and clinical studies suggest prevention of negative impacts from personal and ancestral trauma.
  • Evidence-based trauma treatments, culturally adapted programs, and enrichment are indicated for humans.

Conclusions:

  • Preliminary human data supports a role for transgenerational epigenetics in health disparities.
  • Further research may guide novel interventions for inherited health issues.
  • Addressing ancestral trauma requires acknowledging past harms and implementing systemic policy changes.
