Mesoderm tissue development in Drosophila melanogaster Abstract
... Studying genetics has become a critical area of research as scientists look to gain an insight into human development. Since using human embryos is not a viable option, researchers use model organisms to understand embryonic development. One of the common species used is the fruit fly, Drosophila me ...

In spite of the limited make-up of genes, different transcription units or families of closely related transcription units have been identified in the NRY region during the past decade (see [12–14, 2, 15–18]). Recently, Lahn and Page [3] identified 12 novel genes or gene families and assessed their ex ...

Finding the wheat homologues of genes from model organisms
... It is important to note that the genetic control of traits can vary in plant species. As such, the genetic architecture underpinning traits in model species might not be representative of other plant species. This implies that genes found in model species might not be present in wheat and vice versa ...
