In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...

Studies of genetics conducted in yeast cells, human neurons, mice or other model systems often reveal networks of genes that ...

Computational biologists have uncovered how RNA splicing -- a crucial process for isoform expression and protein diversity -- is regulated across different cell types in the peripheral blood. This ...

The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients experiencing the same infection. How can two people infected by the same pathogen ...

Genetic disorders can occur due to mutations in one gene (monogenic), multiple genes (multifactorial inheritance), and mutation in one or more chromosomes. Point mutations are where one nucleotide in ...

Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA ...

Genes play a role in many human disorders. Some rare disorders are linked to mutations in single genes that follow Mendelian inheritance patterns. Other disorders are regulated by multiple genes, or ...

Many times, scientists embark on a study looking for evidence for a particular hypothesis, and in the process, they come across something totally unexpected and different from their original purpose.
