Is the Delta Symbol Relevant in Genotype Terminology?

AI Thread Summary
The delta symbol is often associated with changes in genotypes, specifically indicating deletions of entire genes or significant portions of them. In genetic notation, the use of the delta prefix before a gene name signifies this deletion. However, it appears that the delta symbol is not commonly seen in printed genotypes, raising questions about its usage and recognition in genetic documentation. The discussion highlights the importance of clear genetic symbols to convey changes effectively.

Sadly enough, I have never seen a delta symbol in front of a printed genotype. Does this mean anymore than the obvious (obvious being some given changed, unstated, to the genotype)?

Capital Greek delta is used to designate a deletions of an entire single gene or a large portion of it and it prefix the gene name.

This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...

Thread 'Fermentation using mixed legume and grain feedstock'

I use ethanol for cleaning glassware and resin 3D prints. The glassware is sometimes used for food. If possible, I'd prefer to only keep one grade of ethanol on hand. I've made sugar mash, but that is hardly the least expensive feedstock for ethanol. I had given some thought to using wheat flour, and for this I would need a source for amylase enzyme (relevant data, but not the core question). I am now considering animal feed that I have access to for 20 cents per pound. This is a...
