Transgenic Drosophila can be created by microinjection of DNA into the embryos. These embryos are at which stage of development?

Transgenic Drosophila can be created by microinjection of DNA into the embryos. These embryos are at which stage of development? Correct Answer Pre-blastoderm stage

Transgenic Drosophila can be created by microinjection of DNA into the embryos. The embryo should be at pre-blastodermal stage. Other developmental stages such as blastoderm and morula follow the pre-blastodermal stage.
