Genetic Screens02:46

Genetic Screens

5.8K
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

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...

The Ratio of X Chromosome to Autosomes02:45

The Ratio of X Chromosome to Autosomes

9.9K
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...

Polygenic Traits01:18

Polygenic Traits

69.2K
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...

Incomplete Dominance01:43

Incomplete Dominance

30.2K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Area of Science:

  • Genetics Education
  • Social Psychology
  • Science Communication

Background:

  • Genetic essentialism is a prejudice assuming shared genetics among racial groups, despite race lacking biological basis.
  • Basic genetics education can inadvertently reinforce genetic essentialism.
  • The Humane Genomics Literacy (HGL) curriculum was developed to counter this prejudice.

Purpose of the Study:

  • To detail the content and pedagogical practices of the HGL curriculum.
  • To provide guidance on adapting the HGL curriculum for university classrooms.
  • To offer a resource for genetics educators interested in implementing HGL.

Main Methods:

  • Describing the original HGL curriculum's structure and teaching methods.
  • Explaining adaptations for university-level instruction.
  • Illustrating the lesson-by-lesson development of concepts and supports.

Main Results:

  • The HGL curriculum has proven effective in enhancing students' genetics knowledge.
  • HGL significantly reduces students' adherence to genetic essentialist beliefs.
  • The article provides an unprecedented look into the HGL curriculum's design.

Conclusions:

  • The HGL curriculum offers a viable pedagogical approach to combat genetic essentialism.
  • Educators can use this guide to integrate HGL into university genetics courses.
  • Improving genomics literacy is crucial for dismantling race-based genetic prejudice.
