AI Thread Summary
Transgenes can be made dominant in genetically engineered organisms by inserting them into germ cells, ensuring that offspring inherit the desired traits. The dominance or recessiveness of an allele is determined by its biochemical function, with gain-of-function alleles typically being dominant and loss-of-function alleles usually recessive. However, there are exceptions, such as dominant negative alleles that can disrupt the function of the wild type allele. Understanding these genetic principles is crucial for effective genetic engineering. This knowledge can guide the development of organisms with specific, inheritable characteristics.

Can we make transgene dominant in the genetically engineered organism so that when it mates the offspring would have the same characteristics?

Yes by insertion of the transgene in the germ cell
 
Whether an allele of a gene acts in a dominant or recessive manner depends on the biochemistry of how the allele functions. In general, most loss-of-function alleles act in a recessive manner and most gain-of-function allele act in a dominant manner. Of course, there are many exceptions, such as dominant negative alleles which can interfere with the function of the wild type allele.

I've been reading a bunch of articles in this month's Scientific American on Alzheimer's and ran across this article in a web feed that I subscribe to. The SA articles that I've read so far have touched on issues with the blood-brain barrier but this appears to be a novel approach to the problem - fix the exit ramp and the brain clears out the plaques. https://www.sciencealert.com/new-alzheimers-treatment-clears-plaques-from-brains-of-mice-within-hours The original paper: Rapid amyloid-β...
