Shotgun sequencing: An approach used to decode a genome by shredding ("shotgunning") it into smaller fragments of DNA which can then be individually sequenced. The sequences of these fragments are then ordered, based on overlaps in the gene Latest Prevention Wellness News Hot Days for U.S. Farm Workers Could DoubleHave a Hangover?

Gene Lethal Definition
Zygotic lethal gene: A gene that is lethal (Stoutal) for the zygote, the cell formed by the union of a sperm (male sex cell) and an ovum (female sex cell). The zygote would normally develop into an embryo, as instructed by the genetic material within the unified cell. However, a zygotic lethal gene scotches prenatal development at its earliest point.
A zygotic lethal gene is a mutated (changed) version of a normal gene essential to the survival of the zygote. The extent of the mutation can range from a change in a single base in the DNA to deletion (loss) of the entire gene.
