A pea plant could have a copy of the height gene that coded for “tall” and a copy of the same gene that coded for “short.” But the tall allele is “dominant,” meaning that a tall-short allele ...

Researchers assessed the role of recessive genetic variants in developmental disorders, suggesting reanalysis of genetic data could improve understanding and diagnosis of conditions for millions of ...

Researchers have conducted what they say is the largest and most diverse study to date on how recessive genetic changes contribute to developmental disorders. The team, headed by researchers at the ...

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 ...

What do Lady Gaga, Barack Obama, Bill Gates, Paul McCartney and Justin Bieber have in common with Ronald Reagan, Jimi Hendrix, Judy Garland, Fidel Castro and David Bowie? They are all left-handed, a ...

Lactose intolerance is a common condition that often has a genetic component that can be inherited. Other cases may result from injuries, medications, or chronic medical conditions. Lactose ...
