hybrid

Studies have found that organisms can inherit mitochondria from male parents in rare instances, and both theoretical and experimental work hint that this biparental inheritance is more than just a fluke.

A genomics study reveals the parentage of a long-mysterious creature called a kunga, the earliest-known hybrid animal bred by humans.

The Yale School of Medicine cancer researcher doggedly pursued the question of how cancer spreads.

Researchers say evidence of hybridization between leukocytes and cancer indicates that this is a primary means of metastasis. Others disagree.

The offspring of crosses between related species can sometimes fill a new environmental niche, and such hybridizations may even lead to speciation.

DNA analysis of a bizarre, 30-year-old whale skull serves as a reminder of the secrets that museum specimens keep about the natural world.

Neither the maternal microbiome nor housing conditions appear to permanently alter which microbes remain in the animals.

The researchers aim to grow transplantable human organs from primate embryos.

The DNA of a whale shows its father was a beluga and its mother was a narwhal.

The hybrid cells promote tumor heterogeneity and possible metastasis, a new study in mice and humans shows.
