gene : a specific sequence of nucleotides in DNA or RNA that is located usually on a chromosome and that is the functional unit of inheritance controlling the transmission and expression of one or more traits by specifying the structure of a particular polypeptide and especially a protein or controlling the function of other genetic material — Webster
Gene is a sequence of DNA or RNA that codes for a molecule that has a function. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism’s offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gene–environment interactions. Some genetic traits are instantly visible, such as eye color or number of limbs, and some are not, such as blood type, risk for specific diseases, or the thousands of basic biochemical processes that constitute life.. — Wikipedia

Genetics is the study of genes, genetic variation, and heredity in living organisms. It is generally considered a field of biology, but intersects frequently with many other life sciences and is strongly linked with the study of information systems. — Wikipedia
Genomics is an interdisciplinary field of science focusing on the structure, function, evolution, mapping, and editing of genomes. A genome is an organism’s complete set of DNA, including all of its genes. In contrast to genetics, which refers to the study of individual genes and their roles in inheritance, genomics aims at the collective characterization and quantification of genes, which direct the production of proteins with the assistance of enzymes and messenger molecules. In turn, proteins make up body structures such as organs and tissues as well as control chemical reactions and carry signals between cells. Genomics also involves the sequencing and analysis of genomes through uses of high throughput DNA sequencing and bioinformatics to assemble and analyze the function and structure of entire genomes.[Advances in genomics have triggered a revolution in discovery-based research and systems biology to facilitate understanding of even the most complex biological systems such as the brain. — Wikipedia

Although only recently recognized as an issue in wildlife ecology, snake fungal disease (SFD) is of emerging concern in the U.S., with parallels among other better-known wildlife fungal diseases such as white-nose syndrome in bats. SFD can be deadly to snakes, and even in milder cases disrupts an animal's abilities to perform normal biological functions such as hibernation, eating and avoiding predators.

Through CRISPR and other gene-editing technologies, researchers and developers are poised to bring dozens—if not hundreds—of new products to grocery stores: mushrooms with longer shelf lives, drought-resistant corn and bananas impervious to a fungus threatening the global supply. A few, including a soybean variety that produces a healthier cooking oil, are already being sold commercially in the U.S.

- Graph pangenomes find missing heritabilityby David Edwards on June 23, 2022 at 12:00 am
Nature Genetics, Published online: 23 June 2022; doi:10.1038/s41588-022-01099-8The use of association studies to identify candidate genes for complex biological traits in plants has been challenging due to a reliance on single reference genomes, leading to missing heritability. Graphical pangenomes and the identification of causal variants help overcome this and provide an important advance for crop breeding.

Nature Genetics, Published online: 23 June 2022; doi:10.1038/s41588-022-01098-9The largest GWAS for kidney function so far provided the starting point for integrated multi-stage annotation of genetic loci. Whole kidney and single-cell epigenomic information is crucial for translating GWAS information to the identification of causal genes and pathogenetic (and potentially targetable) cellular and molecular mechanisms of kidney disease.
