Proof of Genetic Load

Genetic Load: The reduction in selective value for a population compared to what the population would have if all individuals had the most favored genotype. It is normally stated in terms of fitness as the reduction in the mean fitness for a population compared to the maximum fitness.

Mutation Load: Mutation load is caused when a mutation at a locus produces a new allele of either lesser or greater fitness. This lowers the average fitness of the population; a deleterious mutation has a lower relative fitness, lowering average load, while an advantageous mutation effectively lowers the relative fitness of the existing allele, and thus also lowers average fitness.


Special needs often are shown early in life. Here is a forth grade example.

Creationist Criticism: Some creationist (such as Henry Morris)) have suggested that mutational load would increase over time and thus make populations inviable. Morris's continued attacks on evolutionary theory and methodologies is proving his point.


Native America, is a State slogan for Oklahoma. Sometimes it is hard to tell who is a mixed blood in Oklahoma. Other times it is not, especially if the blood is mixed only within the immediate family.


Latimer County Foot bridge. The Police report says he did "walk" out on it first to see if it was safe.

The Calculation:
Genetic load is a number between 0 and 1 and it measures the extent to which the average individual in a population is inferior to the best possible kind of individual. The genetic load equals the relative chance that an average individual will die before reproducing because of the deleterious genes that it possesses. Ignoring frequency-dependent selection, it is calculated as follows:
The general formula for genetic load (L) is as follows:
L = (Wopt - v) / Wopt
If all the individuals in the population have the optimal genotype, then v = Wopt and the load is zero. If all but one have a genotype of zero fitness then v = 0 and L = 1.

To paraphrase the Hen and the Egg "colliery", a Moron is a Moron's way of Making Other Morons.


The police report stated that he claimed by spuenching down he could see through the lattice.



Why is the man smiling? Is it the log between his legs? Could it be his wife and dog were in the pickup cab at the time? One can only hope there are not children at home.



No, No, I have never done this! But I have seen ER do it.

Disclaimer: I did not take these pictures. They were provided by a friend and may be found in many other places on the web. In fact the web hold multiple visual proofs of genectic load.

Ha! I'll have you know that I actually own a pair of ramps for workin' under a vehicle, and plan soon to use 'em to drive Bird's old car up on, to get the passenger door high enough for me to get under there with a drill and put some holes in to drain the water from inside said door.

Great photo essay, by the way.

Enjoyed and understood the photos alright, but "genetic load, chromosomal locus & freqency dependent selection" made me glaze over. Suspect my genetic fitness has gone the way of my physical fitness.....
