Understanding biological relationships is often critical when studying animal populations. Researchers have now developed a transformative approach that identifies stretches of DNA that two ...

Nearly three years ago University of California San Diego researchers announced the world’s first CRISPR-Cas9 genetic editing-based approach to controlling inheritance in mammals. The 2019 achievement ...

Called “Lamarckian Inheritance,” the theory suggests that those experiences can even be passed down to future generations.

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 ...

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 diversity is essential to the survival of a species. It's easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, ...

Corals native to Caribbean waters may have broken a basic tenet of biology. When a mutation occurs in the body cells of nearly any animal on Earth, it’s not passed on to offspring via reproductive ...
