Illustration of human Y chromosome with DNA strands shown inside Scientists have finally filled the gaps in the sequence of the human Y chromosome, 20 years after the first draft of its DNA code ...

FISH analysis using a chromosome 20 paint was performed on the 48 samples with a small 20q deletion. In six cases, the ‘20q deletion’ was revealed to be due to cryptic rearrangements.

Ring 20 is a chromosome anomaly. Instead of being a pair that looks like two sticks, one or both arms of the 20th chromosome are joined at the ends, making them look like a ring under the microscope.

We don't know exactly why men are taller than women on average, but we have some genetic clues. On average, human males tend ...

Scientists fully sequence the Y chromosome for the first time, uncovering information that could have implications for the study of male infertility and other issues.

Several closely located markers (D20S109, D20S178, D20S197, and D20S481) also showed evidence of linkage. Markers in other parts of chromosome 20 did not show evidence of linkage with type 2 diabetes.

Then they measured gene expression in the hippocampus, a key brain region for learning and memory that deteriorates during aging, in 20-month-old female mice, akin to 65-year-old humans. Surprisingly, ...

The male Y chromosome has disappeared from a species of rat, leading scientists to investigate how humans might also lose ours in the near future.. It's not all bad news for men though, as a paper ...

Another important finding was that IM cells often have chromosome 20 gain and can grow without attaching to a surface -- traits typically associated with cancer cells that facilitate tissue spread.

Soon, about 20 independent papers showed associations between loss of the Y chromosome in blood cells and heart disease, shortened life spans and various age-related diseases like solid tumors and ...

The Y chromosome was once used to label people as criminal. A new complete Y chromosome sequence just might combat this dangerous myth. ... Throughout the 20 th century, ...

The work reveals a complete catalog of the genes in the male sex chromosome — the last human chromosome to be fully sequenced — and how they're organized.. The findings, published Wednesday ...
