Genomics

36.3K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

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...

Incomplete Dominance

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.

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Genomic Imprinting and Inheritance

34.4K
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

Genetics education needs to move beyond simple Mendelian inheritance. This approach counters outdated, essentialist views of heredity and promotes a more nuanced understanding of biological inheritance.

Area of Science:

  • Genetics and Heredity
  • Evolutionary Biology
  • Developmental Biology

Background:

  • Traditional genetics instruction often oversimplifies inheritance using Mendelian concepts.
  • Essentialist views of heredity, which suggest fixed, inherent traits, are prevalent and scientifically inaccurate.
  • A broader perspective is needed to accurately represent the complexity of biological inheritance.

Purpose of the Study:

  • To advocate for an instructional shift in genetics education beyond the confines of Mendelian genetics.
  • To address and correct inaccurate, essentialist perspectives on heredity.
  • To promote a more comprehensive understanding of genetic principles.

Main Methods:

  • Review of current genetics curricula and common pedagogical approaches.
  • Analysis of historical and philosophical underpinnings of essentialist views in biology.
  • Synthesis of modern genetic concepts (epigenetics, polygenic inheritance, gene-environment interactions) for educational integration.

Main Results:

  • Mendelian genetics alone provides an incomplete and potentially misleading framework for understanding inheritance.
  • Essentialist viewpoints are perpetuated by an overreliance on simplified Mendelian models.
  • Integrating broader genetic concepts can foster more accurate and sophisticated student understanding.

Conclusions:

  • Genetics education must evolve beyond Mendel to accurately reflect biological complexity.
  • Moving beyond Mendelian frameworks is crucial for dismantling inaccurate, essentialist views of heredity.
  • A modernized approach to genetics instruction is vital for scientific literacy.
