Hermann J. Muller (1890–1967), who was a 1946 Nobel Prize winner, coined the terms amorph, hypomorph, hypermorph, antimorph and neomorph to classify mutations based on their behaviour in various genetic situations. These classifications are still widely used in Drosophila genetics to describe mutations. For a more general description of mutations, see mutation, and for a discussion of allele interactions, see dominance relationship.
Key: In the following sections, alleles are referred to as +=wildtype, m=mutant, Df=gene deletion, Dp=gene duplication. Phenotypes are compared with '>', meaning 'phenotype is more severe than'
Loss of function
Amorph
Amorphic describes a mutation that causes complete loss of gene function. Amorph is sometimes used interchangeably with "genetic null". An amorphic mutation might cause complete loss of protein function by disrupting translation ("protein null") and/or preventing transcription ("RNA null").
An amorphic allele elicits the same phenotype when homozygous and when heterozygous to a chromosomal deletion or deficiency that disrupts the same gene. This relationship can be represented as follows:
Parallel is a video feature compiling all of R.E.M.'s Automatic for the People and Monster-era promotional videos, as well as several recorded for this release alone. It was released on video on May 30, 1995, and on DVD format on August 22, 2000, both on the Warner Brothers label.
The release, which runs at 70 minutes, features promotional videos to all of the band's singles from Automatic for the People and all but one from Monster ("Tongue" had not been released as a single until after this compilation). Also included are several avant-garde clips excerpted from 1995 tour films, ranging from ten seconds to two minutes, playing in between each song, as well as an A–Z of R.E.M. at the end of the feature.
There are no bonus features on the DVD; however, there is an optional lyrics subtitle track. Audio on the DVD-5 is PCM Stereo. The DVD was certified "15" in the UK due to nudity in 'Nightswimming'.
There were two versions released in the US. The "A Version" cut out the nudity from "Nightswimming," while the "D Version" contained the uncut video. A Parental Advisory warning was placed on the cover of the "D Version."
Components of an electrical circuit or electronic circuit can be connected in many different ways. The two simplest of these are called series and parallel and occur frequently. Components connected in series are connected along a single path, so the same current flows through all of the components. Components connected in parallel are connected so the same voltage is applied to each component.
A circuit composed solely of components connected in series is known as a series circuit; likewise, one connected completely in parallel is known as a parallel circuit.
In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.
Consider a very simple circuit consisting of four light bulbs and one 6V battery. If a wire joins the battery to one bulb, to the next bulb, to the next bulb, to the next bulb, then back to the battery, in one continuous loop, the bulbs are said to be in series. If each bulb is wired to the battery in a separate loop, the bulbs are said to be in parallel. If the four light bulbs are connected in series, there is same current through all of them, and the voltage drop is 1.5V across each bulb, which may not be sufficient to make them glow. If the light bulbs are connected in parallel, the currents through the light bulbs combine to form the current in the battery, while the voltage drop is across each bulb and they all glow.

Lumping them all into a single amorphous category and attempting to draw tortured parallels between them diminishes their singularity and denies the authenticity of survivors’ memories.
... of an office job or how certain points in one’s life run parallel with specific and stifling expectations—a theme made all the more prescient by the amorphous nature of life under the pandemic.
