Cited by 2 •
2010
Genetic associations often remain unexplained at a functional level. This method aims to assess the effect of phenotype-associated genetic markers on gene expression by analyzing cells heterozygous for transcribed SNPs. The technology allows accurate measurement by MALDI-TOF mass spectrometry to quantify allele-specific primer extension products.

Accrual Basis of Accounting

2025
Accrual basis accounting records revenues and expenses when they are earned or incurred, regardless of when the associated cash is received or paid. This approach emphasizes the economic substance of transactions, aligning financial reporting with the actual timing of business activity rather than the cash flow timeline. Accrual accounting provides a comprehensive and consistent view of financial performance by recognizing income when goods or services are delivered and expenses when they...

Cash Basis of Accounting

2025
The cash basis of accounting records revenues and expenses strictly based on the timing of cash transactions. Under this approach, income is recognized only when cash is received, and expenses are recorded only when payments are made. This method deviates from accrual accounting, which recognizes revenues when earned and expenses when incurred, regardless of cash movement.The primary appeal of the cash basis lies in its simplicity. It suits small businesses, sole proprietors, and service-based...

Genetic Crosses

2023
To dissect genetic processes or create organisms with novel suites of traits, scientists can perform genetic crosses, or the purposeful mating of two organisms. The recombination of parental genetic material in the offspring allows researchers to deduce the functions, interactions, and locations of genes. This video will examine how genetic crosses were influential in developing Mendel's three laws of inheritance, which form the basis of our understanding of genetics. One genetic crossing...

An Overview of Genetics and Disease

2023
Many human diseases are associated with mutations or variations in genetic sequences. Some of these genetic variants are heritable, passed down from generation to generation, while others arise sporadically during an organism’s life and cause diseases such as cancer. Researchers are trying to identify and characterize these genetic alterations in the hopes of improving diagnosis and therapeutic options for patients.In this video, we will examine the history of genetic disease research, and...
FAQs
Gene-environment interplay helps explain why inherited influences do not operate in isolation. Environmental conditions can interact with genetic variation, while developmental processes shape how those effects emerge over time. In psychology, this framework helps researchers examine individual differences as outcomes of biological and environmental influences together, rather than treating genes as a complete explanation for behavior.
Several biological pathways can connect genetic variation with psychological traits. The overview specifically identifies neurotransmitter activity and brain development as examples of processes through which genes may influence cognition, personality, or mental health. Examining these pathways gives psychological research a mechanistic bridge between DNA differences and observable outcomes, while keeping attention on developmental change.
Heritability estimates are used to quantify the contribution of inherited variation to differences observed among individuals. They do not by themselves identify a single responsible gene or explain a person’s outcome. Within psychological science, such estimates are most informative when considered alongside environmental conditions, developmental processes, and molecular evidence about associated genetic factors.
Researchers approach the genetic basis of psychological traits at several levels. Twin and family studies estimate heritability, whereas molecular genetics and genome-wide analyses seek genetic factors associated with traits or conditions. Using these approaches together can connect broad inheritance patterns with more specific biological evidence relevant to cognition, personality, and mental health.
A study may begin by selecting a psychological outcome such as cognition, personality, or mental health, then use twin or family designs to estimate heritability. Molecular genetics or genome-wide analyses can next examine associated genetic factors. Researchers interpret these findings with environmental and developmental information to build a more precise account of individual differences.
Findings can support risk assessment and contribute to more personalized approaches to prevention and treatment. Their value extends beyond prediction: identifying links with cognition, personality, and mental health can also refine models of psychological development. These applications are strongest when genetic evidence is interpreted with environmental conditions and developmental processes.
