What're the advantages of bulk population selection?
353324
With this method of selection the offspring from a crossing are planted at planting densities equal to commercial planting densities. During this period, which may include a number of generations, the level of homozygosity in the bulk population increases.\n\nThis method is simple and cheap and involves less work than pedigree selection in the earlier generations. It is necessary to plant large populations to ensure that the best segregates are selected when selection starts. Segregating generations are subjected to another single plant selection step. Fewer records are kept during earlier generations than with pedigree selection. This type of selection is especially carried out with crops which are usually planted at high planting densities, e.g. small grain crops.

The obvious advantage of asexual reproduction is that you don't need other members of your species around to reproduce.  This is a really good thing if you want to go in and colonize someplace like a island, or maybe a recently-burned forest.  Or if your species isn't doing so great and there's just no one else around.\n\nFrom an evolutionary perspective, the 'goal' of an organism is to pass it's genes on to the next generation.  In sexual reproduction, each organism only gets to pass half its genes to its offspring.  In asexual reproduction, the parent gets to pass all its genes to the offspring.  That's great if the parent is perfectly adapted to its environment.  The problem is, it's the evolutionary equivalent of putting all your eggs in one basket - if something chances and the offspring are no longer well suited to the environment, chances are they'll all die instead of just a few.

wait a year, the market sucks on bulkers.  maybe try moving to brazil, peru, australia, or china

1) disadvantages:\n- comparability and availability (3 way- stick)\nin the regions where census data is problematic, it's availability can be a problem, and, obviously, this introduces unreliability into your estimations based on statistical methods;\nin the regions like US secondary data is so widely available that one has to posess superior ability to analyze it to be able to extract advantageous information about consumer behaviour not already extracted by competitors)\n- explanatory power\nif consumers are grouped by one demographics, say, age, there's ambiguity as to whether consumers at the border ages are sufficiently different to place them in separate groups;  also, you can not split them into groups to no limit - therefore you lose information about consumers if you group them based on limited demographics;\n\n2) advantages:\n- availability\nin countries like US secondary demographical data IS the cheapest (free) data to get;\n- in developed countries, with some effort and good statistical software, for generic products, especially, demographical data can explain up to 70% of change in consumer behaviour\n\n\n- this is not all, but everything I remember from my marketing course

advantage is size and one-stop shopping... disadvantage is competivity pricing on some of thier products

Do a web search for the parameters.  We would need much more information from you on sample types, volumes, etc and you capabilities, instrumentation available, etc.  All of these are factors in deciding a method.

I've also heard of studies similar to those you're referring to; I agree 100% w/ you that high population density is a pretty feasible reason for homosexuality and violence, these may well be nature's "control mechanisms" for avoiding LOCAL overpopulation. As far as the whole world being overpopulated, I don't agree w/ you.... food production nowadays, for example, could feed more than 100% of the world's population adequately if equally spread among all human beings; furthermore, global birth rates are rapidly declining, which could actually lead to global UNDERpopulation just a few centuries from now.

All it has to do is not have a massive penalty, it can be totally useless provided that the population is not very strongly stressed or it uses little extra energy.  If it's a liability it will tend to be selected against but something that's useless doesn't necessarilly put the organism in much more risk.

People migrate for economic reasons, better livelihood, better healthcare, better education, basically progression in life.\n\nThe advantage is that people send money home and people develop new skills abroad that may better the people

There is no maximum as long as they are your client base and they have asked to receive email from you.\n\nSend it to the wrong people and you will be relegated to the bulk folder in no time.
