Despite the immense amount of genetic material present in each cell, around 3 billion base pairs in humans, this material ...
In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y chromosome, she wrote two years later in a commentary, "is running out of time." The male-determining sex ...
There are 23 pairs of chromosomes in the human body. This includes 22 pairs of autosomal or somatic chromosomes that are common to both men and women and one chromosome that differs according to what ...
A research paper highlights how spiny rats have developed a new male-determining gene. A recent study suggests a surprising future for human reproduction: the Y chromosome, which is crucial for ...
Sex chromosomes are unusually labile systems, with frequent shifts between male and female heterogamety and with a large variety in the precise number and types of chromosomes. The lability is further ...
Chromosome 4 is the fourth largest of the 23 pairs of chromosomes in humans. Chromosome 4 is made up of over 186 million base pairs, the building blocks of DNA which are tightly packed and super ...
PacBio (NASDAQ: PACB), developer of the world's most advanced sequencing technologies, today announced CiFi, a new community-developed method that enables chromosome-scale, haplotype-resolved genome ...
What was once the final frontier of the human genome -- the Y chromosome -- has just been mapped out in its entirety. Scientists used advanced sequencing technologies to read out the full DNA sequence ...
The good news is two branches of rodents have already lost their Y chromosome and have lived to tell the tale. A new paper in Proceedings of the National Academy of Science shows how the spiny rat has ...
The Y chromosome is perhaps the most puzzling part of the human genome. Associated with male development, it is chock-full of repetitive and inverted stretches of DNA, a hurdle that makes it ...
Karyotype tests take a close look at the chromosomes inside your cells to see if anything about them is unusual. They’re often done during pregnancy to spot problems with the baby. This type of ...
