Population genetics - make inferences from allele frequency

... populations across a whole species distribution is 0.75 or 0.5, can you make any inference about something like dominant-recessive relationship or lethal homozygotes? I assume random mating (no sexual selection), diploid, no drift (genetically well connected) or something that meets Hardy-Weinberg ...

mutation-selection balance

... Carey and Bamshad: Consider, for example, a dominant disease that results in death before the person can reproduce. This is termed a genetic lethal mutation because, even though the individual might survive for some time, he or she contributes no genes to the next generation. Each time mutation ...

Synthetitic genetic screening in yeast

... into a car but not drive it (let's call it a different phenotype). Let's for purposes of analogy also equate being unable to access the car with lethal phenotype (as car is useless). Now, in this situation you need to lose BOTH key and alarm button to get "lethal" phenotype... People ...

Re: Re:

Rap: DNA does not evolve into mutation-resistant. Simply if the mutation would be lethal then nothing with mutated DNA survives thus it seems like mutation resistant. Also, the identical DNA strains have identical geometry (whatever that should mean) and, at least ...
