To help elucidate the reproductive characteristics of the Atlantic snow crab Chionoecetes opilio, the functional anatomy of the male reproductive system and the female spermatheca was investigated ...

The structure and function of the reproductive tracts of the spider crab Inachus phalangium were investigated, focusing on sperm transfer, sperm storage in the seminal receptacles, and spawning. Males ...

Human reproduction requires both male and female gametes. Gametes are special sex cells that contain the genetic information necessary to create a new life. Men produce millions of gametes called ...

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 ...

Researchers have recently identified and described a new genus and species of xanthid crab found in Okinawa Island, Ryukyu Islands, Japan. Named Mabui calculus, it is the first among the 7,800 species ...

Reproduction and dispersal are key aspects of species life history that influence spatial genetic structure in populations. Several ant species in the genus Cataglyphis have evolved a unique breeding ...

Researchers from the Yong Loo Lin School of Medicine at the National University of Singapore (NUS Medicine) and CHA ...

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which was first discovered in patients with severe pneumonia at the end of 2019, has since infected over 272 million worldwide and ...
