The so-called "50/500 rule", where a population needs 50 individuals to prevent inbreeding depression, and 500 individuals to guard against genetic drift at-large, is an oft-used benchmark for an MVP, but a recent study suggests that this guideline is not applicable across a wide diversity of taxa. [4] [3]
Foster's rule, the island rule, or the island effect states that members of a species get smaller or bigger depending on the resources available in the environment. [ 28 ] [ 29 ] [ 30 ] The rule was first stated by J. Bristol Foster in 1964 in the journal Nature , in an article titled "The evolution of mammals on islands".

This "Rule of 70" gives accurate doubling times to within 10% for growth rates less than 25% and within 20% for rates less than 60%. Larger growth rates result in the rule underestimating the doubling time by a larger margin. Some doubling times calculated with this formula are shown in this table. Simple doubling time formula:
The 50% rule is simple: You only put in 50% of the effort toward your goal. In other words, take your goal, whatever it is, and slice it in half. Related: Behaviors that will keep you healthy this ...
The proper way of applying the abstract mathematics of the theorem to actual biology has been a matter of some debate, however, it is a true theorem. [3] It states: "The rate of increase in fitness of any organism at any time is equal to its genetic variance in fitness at that time." [4] Or in more modern terminology:

Chargaff's second rule appears to be the consequence of a more complex parity rule: within a single strand of DNA any oligonucleotide (k-mer or n-gram; length ≤ 10) is present in equal numbers to its reverse complementary nucleotide. Because of the computational requirements this has not been verified in all genomes for all oligonucleotides.
