Eye color is a complex genetic trait determined by pairings of genes passed on from each parent. Scientists once believed eye color was determined by a single gene, but advances in genetic research ...

Males usually have one X and one Y chromosome, while females have two X chromosomes. The mammalian Y chromosome, though small, contains several gene families involved in spermatogenesis and fertility.

X chromosomes, some researchers hypothesize, could help explain sex differences in cognition, verbal memory, or brain disease risk. “Given the fact that the X chromosome is enriched for brain-related ...

Feb. 19, 2025 — Researchers have found a compound in ginger, called furanodienone (FDN), that selectively binds to and regulates a nuclear receptor involved in inflammatory bowel disease (IBD ...

Here, the authors identify evolutionary adaptation in the Andean Aymara that modulates NF-κB and HIF signaling, explaining elevated hemoglobin levels and suggesting its protective role against ...

Genetics is the branch of science concerned with genes, heredity, and variation in living organisms. It seeks to understand the process of trait inheritance from parents to offspring, including ...

Feb. 20, 2025 — Biologists have discovered a new type of RNA-splicing regulation that helps to determine which protein-coding exons will be included in messenger RNA ...

Klinefelter syndrome is a genetic condition that affects only males. Here's what you should know about the causes, symptoms, and treatment options for the condition. Klinefelter syndrome is a genetic ...

Scientists have discovered that some tiny segments of RNA thought to be junk instead have a functional role in suppressing production of certain messenger RNAs and appear to help cells respond to ...

By inserting within a coding-sequence they may inactivate the gene, or by inserting upstream of a gene they may modify its expression. ISs may also help integration of plasmids into the chromosome of ...

Vitamin E is an effective method for treating hair loss. A small study revealed that people taking vitamin E supplements for ...
