The study published in Nature describes a statistical method used to identify at least 30 parent-of-origin effects in 14 genes, demonstrating genetic variation between maternal and paternal inheritance.

The modern form of the gene ADSL in humans reduces enzyme stability compared to that found in Neanderthals or Denisovans, suggesting significant biochemical differences between species.

Obsessive-compulsive disorder (OCD), once mischaracterized as demonic possession, is recognized today as a multifaceted psychiatric disorder affecting an estimated 2 percent of the population.

Large-scale genome-wide association studies have identified many complex trait loci related to autoimmune, metabolic, and infectious diseases, yet assigning function to non-coding variants remains challenging.

In families with three boys, there is a 61% chance that the next sibling is male, while families with three girls have a 58% chance of another female.

Genetic analysis reveals that flying foxes possess a unique set of genes associated with their enormous wingspans. These genetic factors influence their growth and adaptation to island ecosystems.

Qimmit - a type of sled dog that has been kept by Inuit in Greenland for nearly 1,000 years - don't share much DNA with wolves, despite a reputation for having been interbred.

Scientists believe that hybrid children would inherit traits from both of their parents. This means hybrids might have a Neanderthal's long arms and short legs with the smaller skull of a Homo sapiens.

Hair growth is primarily determined by genetics, with thickness, length, and growth rate being largely influenced by inherited traits. Experts agree that no product can significantly alter these genetic limits.

The website took on a life of its own, showcasing the ongoing evolution and impact of the UCSC Genome Browser, vital for genomic research.

In this study, we report the generation of fertile androgenetic mice. Our findings, together with previous achievements of uni-parental reproduction in mammals, support previous speculation that genomic imprinting is the fundamental barrier to the full-term development of uni-parental mammalian embryos.

A new study reveals that iron-deficient pregnant mice can have genetically male fetuses that develop ovaries, challenging the notion that biological sex is solely determined by sex chromosomes.

People often carry emotional patterns, strengths and vulnerabilities from their ancestors - and there is some evidence that these can be physically passed down.

Cellular memory refers to the ability of cells to encode, store, and retrieve information, which could significantly impact how we understand organ transplantation.

Measuring Lp(a) can help identify someone who should be paying more attention to their cardiovascular risks, leveraging personal genetics for better health assessments.

Typically, people think about robots as devices that you build with plastic and metal and the wires and software. But because fruit flies are so well understood, they can be treated as living robots.

This study uncovers 8.7 million undocumented genetic variants in Brazil, filling a significant gap in genetic research, particularly for diverse and complex populations.

Dr Thivos Sokratous emphasizes that male pattern hair loss is influenced by genetics and hormones, with the androgen receptor gene being a significant factor, but it's more complex.

BAIER: I don't know. I think it's genetics. It's good genetics. I had a father who was very strong, and I had a mother who was very strong. TRUMP: They lived to ripe old ages, and they were great people.

"These cases don't appear to be related to fat, so we want to try and understand what's going on. Is it genetics? Or due to how the pancreas has developed?"

"Scientists say the odour is down to small changes in an enzyme that prevents bad breath in humans, illustrating a simpler evolution of traits than expected."

The study reveals that every child inherits new mutations unknown to their parents, which raises significant questions about the genome's evolution over generations.

A traditional practice of cold-water diving on Jeju Island has influenced the genetic makeup of its inhabitants, suggesting cultural habits can shape human evolution.

Over many generations - through deliberate selection, crossing and interbreeding - humans 'created' the domesticated creatures we have and use today.

For now, the Curiously Isolated Hairstreak reminds us that even the smallest and most overlooked species can hold extraordinary scientific and conservation significance.

The study revealed that while Phoenician civilization spread its culture across the Mediterranean, its inhabitants did not share a common Middle Eastern ancestry.
