What are maternal-effect genes?

Video transcript

Hello, everyone. Here we have a question asking which one of the following is a maternal effect gene. So what is a maternal effect gene as we've talked about in previous videos, maternal effect genes are genes that are expressed in the mother and controlled the early development of the embryo. They're typically transcribed and translated into M RNA and protein in the mother's oocyte and then are stored in the egg cytoplasm for use during early embryonic development. One of these is a big coi gene in Drosophila, Melina gaster. So our answer here is c bike hygiene. Now that we're on the topic of Bitcoin genes by coy genes encodes a transcription factor that is localized to the anterior end of the developing embryo. This localization is critical for establishing the anterior posterior axis of the embryo as the concentration of Bitcoin protein decreases from the anterior to the posterior end of the embryo. So again, our answer is C by coin jean. Thank you for watching. Bye.
