Polygenic Traits

67.3K
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...

CRISPR01:59

CRISPR

53.9K
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

Genomic Imprinting and Inheritance

35.8K
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...

Summary
This summary is machine-generated.

Embryo selection based on polygenic scores (ESPS) offers predictions but has limited accuracy and potential risks. Further societal discussion is needed for this evolving reproductive technology.

Area of Science:

  • Reproductive Medicine
  • Genetics
  • Bioethics

Background:

  • Companies offer embryo selection based on polygenic scores (ESPS) for in vitro fertilization.
  • Polygenic scores use adult genomewide association studies to predict outcomes.

Purpose of the Study:

  • To discuss factors limiting polygenic score predictive power for embryo selection.
  • To quantify these limitations for various traits.
  • To explore potential unintended consequences of ESPS.

Main Methods:

  • Analysis of factors affecting polygenic score accuracy in embryo selection.
  • Quantification of predictive power limitations for clinical and nonclinical traits.
  • Discussion of ethical and societal implications.

Main Results:

  • Polygenic scores have limited predictive power for embryo selection due to various factors.
  • Potential risks include selecting for adverse traits and exacerbating societal inequalities.
  • The technology may alter population demographics and devalue certain traits.

Conclusions:

  • Responsible communication regarding ESPS is crucial for practitioners.
  • A broader societal conversation is necessary to address the implications of ESPS.
  • The limitations and risks of ESPS require careful consideration.
