Directional selection
What is the definition of sample referring to the mathematical term?
A selection taken from a larger group (the "population") so that you can examine it to find out something about the larger group.
What is the average horizontal iris diameter?
The average diameter of an iris is 11.8mm, with the majority of the population falling between 10.2mm and 13.00mm, on the larger end.
Which has a larger population Houston or Omaha?

How does overpopulation relate to natural selection?
Natural selection is the nonrandom process by which biological traits become either more or less common in a population as a function of differemtial reproduction of their bearers. One of the main processes by which natural selection takes place is the competition over resources. The larger the population in a certain area, the more competition takes place. In the long run, it doesn't matter wheather or not the area is overpopulated; within any and every population, competition over resources takes places, so, in turn, natural selection does, too.

What are the 5 ways a population can evolve?
A population will most likely evolve when there is a small population, mutations exists, natural selection may take place, nonrandom mating occurs, and/or gene flow may occur. Sexual selection, genetic drift, Gene flow, Mutation, and natural selection are five ways a population can evolve. Sexual selection is natural selection arising through preference by one sex for certain characteristics in individuals of the other sex. Genetic drift is variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce. Gene flow is the transfer of alleles or genes from one population to another. Mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.

When organisms with desirable characteristics are mated by humans what is it called?
This is called Artificial Selection. Artificial Selection is the source of most modern produce and meat. For instance, corn is has been artificially selected to have larger kernels and cobs to provide more food. One theorized origin of Corn is a small grass bush called teosinte. Artificial selection is not entirely beneficial however. Certain Dog Breeds subjected to generations of artificial selection have developed propensities for painful and deadly illnesses. Heart, muscular, respiratory, and neurological dysfunctions number among the problems some breeds experience. Charles Darwin studied artificial selection by breeding traits in pigeons.
