How important is gene flow for maintaining a species' identity and diversity, ... then the resulting hybrid offspring would produce seeds that were unusable for market purposes or for selecting ...

The detected gene flow among bears also questions the basic biological concept of a species. The biological species definition assumes that different species cannot produce offspring in the wild ...

How much gene flow is there between plant populations? How important is gene flow for maintaining a species' identity and diversity, and what are the implications of these processes for evolution ...

I n a world first, scientists have created mice with two fathers, capable of having offspring of their own. It’s a huge step ...

Mice with two fathers and no mother have now had offspring of their own. The study is a breakthrough in androgenesis – that ...

Researchers used epigenome engineering and CRISPR to reprogram sperm DNA, allowing embryos to develop with only fathers.

Gene activity is regulated by many things, including epigenetic factors, which can include chemical marks that adorn DNA, or structural changes that alter gene expression. But epigenetic marks do not ...

Plant scientists have used a standard "gene gun" since 1988 to genetically modify crops for better yield, nutrition, pest resistance and other valuable traits.

Mendelian genetics provides insights into how traits are inherited through the transmission of genes from parents to offspring. The concept involves the study of dominant and recessive traits, as ...

Scientists are gathering evidence that suggests emotional trauma can transcend generations by altering how genes in the offspring are switched on and off Photograph by Tek Image, Science Photo Library ...

Iron deficiency in pregnant mice may lead to the development of ovaries in a small proportion of offspring carrying XY chromosomes, which typically determine male sex. The findings, published in ...

By observing the length of the Neandertal DNA segments, which is related to the number of generations since the gene flow, the researchers inferred that the gene flow began about 50,000 years ago and ...
