Scientists found that fruit fly embryos can develop through multiple genetic paths, not just one. This challenges traditional ideas.

The mammalian OGT gene is located on the X chromosome, and it is known to be essential for early development ... in the journal PLOS Genetics. Embryos with milder OGT mutations survived, but ...

The findings help elucidate what happens during the earliest periods in development. “I was always interested in how cells decide their fate,” Zernicka-Goetz said. In the mouse developing embryo, she ...
