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 ...

An expert has shed light on the question of whether cognitive decline can be inherited, at a time when over six million Americans are living with dementia. Dr Kellyn Lee, a research fellow and ...

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 ...

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 ...

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 ...

Almost 50 more genes have been flagged as being linked to Alzheimer’s, along with changes in activity in crucial cells 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 ...
