Polygenic Traits01:18

Polygenic Traits

68.7K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Behavioral Genetics and Its Designs

908
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

Genetic Screens02:46

Genetic Screens

5.5K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Human Genetics

1.3K
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Genomic Imprinting and Inheritance

36.6K
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...

Area of Science:

  • Reproductive medicine and genetics.
  • Bioinformatics and predictive modeling.

Background:

  • A company now provides comprehensive genetic analysis for embryos during in vitro fertilization (IVF).
  • This analysis generates polygenic scores to assess disease risks.

Discussion:

  • The implementation of polygenic scores for embryo selection presents complex ethical dilemmas.
  • Balancing predictive potential with societal values is crucial.

Key Insights:

  • Polygenic scores can possess substantial predictive capabilities when accurately derived.
  • Embryo selection based on genetic data is now a practical reality.

Outlook:

  • Further research is needed to refine polygenic score accuracy and clinical utility.
  • Societal discourse on the ethical implications of genetic embryo selection must continue.
