It's a recessive gene on the X chromosome.

In females this means that it only expresses if both chromosome have the orange gene.

Since males only have one X chromosome it always expresses if present.

The orange males to female ratio in a population will average around 4:1.

The author was confused and that was written poorly. It is a mutation. A mutation is any change to the DNA sequence. Specifically it's called a point mutation deletion. A point mutation is a small mutation of one nucleotide.

The recipe for proteins on DNA is stored as a 3 nucleotide code. 3 nucleotides represent 1 amino acid (A protein is a chain of amino acids). A small deletion (1 or 2 nucleotidds) in the active coding sequence messes up the entire sequence.

Not really. Although the genetic diversity across the entire continent is higher, limits to mate selection is common. Location, culture, economics, language, etc, all limit the genetic pool that people have to choose a mate from. So in-group inbreeding is relatively common.

Humans have lived in smaller groups with limited mate choice for most of our evolutionary history. A lower level of inbreeding improves fecundity (around 4th cousins). Once the inbreeding coefficient gets to around 2nd cousins, that's when problems arise. This happens often in small tribes.

Smaller polygamous groups quickly develop issues with inbreeding. The entire group often has an inbreeding coefficient around 1st cousins or even siblings (example - polygamous Mormons).

Now Uganda is a bit different because the polygamous group is large. This limits inbreeding effects.

has not been peer reviewed.

Then I read their methods ... It should not pass peer review. Their variable control is shit.

But..... we don't have unlimited hectares of suitable land for people to fuck up. That's the point.... A food forest concept would require every last bit of ariable land on the planet and still not provide enough food for everyone.

The entire idea shows a complete lack of understanding what it takes to feed people at the scale of billions.

Agriculture is water intensive. The more land we use, the more water we need. Whether from the sky or from a irrigation canal, it's still water used to grow crops not native environments. Reducing our land footprint reduces our total water usage. That's what matters, not the per hectare usage.

Corn and wheat - just irrigating itincreases the average yield by 2x to 10x depending on the region.

If you've never been in a 50 hectare greenhouse it's hard to imagine (they are 12-15m tall). These greenhouses are all in soil as well. The larger a greenhouse is the more efficient it is as maintaining temperature. You can get 2-3 cycles per year in them depending on light levels. So the yields are irrigated + 50% per cycle and 2-3 cycles per year instead of 1 cycle. Supplemental lighting can push it to a solid 3 cycles.

We need food for billions not a small community.

Food forest = lower environmental impact per acre but a higher environmental cost per kg of production. It's also highly environmentally irresponsible to add in invasive species, disease, and pests into and established ecosystem. These are all spread by seed, soil, and plant tissue of the crops we grow.

Irrigated and/or protected culture... Protected culture for the crops that make sense. Irrigated in for all others.

We farm the way we do because historically we go through periods of innovation then stagnation. When the way we farm no longer works and we either rapidly innovate again or the civilization flounders and dies due to famine and war.

"Enormously expensive," it's all in perspective. It's damn cheap compared to the cost of the environmental damage we are currently doing. FYI The equipment and technology already exist to do it as well.

Have played every version of BF since it came out. Haven't purchased or played BF2042 since they abandoned BF1 & BF5 still full of bugs.

EA doesn't give a fuck about the quality of their games anymore. To be fair, none of the major studios do anymore. They are too big and try to race through development to make sure that this years sales numbers are bigger than last year's.

The best thing for the environment and soil health is to not farm it. There is no such thing as environmentally friendly agriculture. It is always destructive.

We farm the land we do because it's profitable.

Irrigated acres make up less than 7% of the land area used for agriculture but produce 65% of the total yield.

Protected culture (greenhouses, high tunnels, etc) produce 10x to 20x more per acre than open field production.

Increasing our water storage and transport infrastructure on a massive scale, combined with expansion of protected culture could reduce our agricultural land requirements by as much as 80%. All wiithout changing our diets.

Imagine 80% of the farmland rewilded? Massive stretches of native ecosystems rebounding without fertilizer or sprays.

The 2020's are looking to end like the 1920's.

Not a recession, but a massive depression.

Hmmm...

That would make more sense. The distinctive backpack must have made him easily traced by cameras.

Why would he do that?

Either he was incompetent or he knows the art of misdirection. A mask that he knowing allowed to be seen would send the authorities on a wild goose chase. All of the cops would be looking for the wrong person for a long time.

A quick change, ditch all the distinctive outfit, and change into a non-descript Walmart outfit. Then take care to let no camera see his real face as he high-tails to a safe location.

He assassinated an immoral asshole who has profited on the needless pain, suffering, and death of millions.

The reaction can't be too surprising.

Hmmmm... I wonder what would cause pharmaceutical prices mysteriously drop?

Since my self-employed income is seasonal (the work is constant), I get to do that for around 9 months of the year. It gets old.

It cost at last 50 million in a fancy name designer fees.

Or be in a religious cult like Mormons. Of course they will send you to a foreign country and confiscate your passport until your 1.5-2 years are over.

Fun fact: Organic production is worse for the environment overall.

It's less damaging per hectare under cultivation, but more hectares are required to produce the same yield. So it's more damaging per kg of production.

FYI there is only two suppliers of carrots in the U.S.: Grimmway and Bolthouse.

This one is Grimmway.

So if you have organic carrots, double check on this one.

If I recall correctly they linked a bunch of powermacs together with FireWire.
