What is an example of genes becoming more common in a population?

One example of a gene becoming more common in a population is antibiotic resistance in bacteria. When the antibiotics kill the bacteria some have a mutation that makes them resistant. These bacteria then reproduce and over time the species genetic code changes so that they are antibiotic resistant. This is the reason new vaccines are constantly released. The same basic principle works in pesticide resistance of rats.

Are similar genes evidence of common ancestory?
If organisms have similar genes, then they are closely related.
Recessive allele is more common or dominant allele?
Not necessarily. I think the dominant genes are more common, but there are lot of exceptions out there. For example, having six fingers in humans is a dominant gene, but it isn't all that common.
Why do common patterns of genetics control development exist among animals?
They exist because all these genes have descended from the genes of common ancestors.
How does population change as a result of natural selection?
Natural selection is not a thing that acts on populations, it is a tendency for harmful genes to not be passed on (die out) and useful variations to thrive and become common.
Name a characteristic that is determined by genes alone?
One example of a characteristic that is determined by genes is hair color.
What is gene flow?
Gene flow is genes moving between two populations. the transfer of genes from one gene pool to another two populations transferring genes
How can genes be removed from the gene pool?
Individuals leaving the population removes genes
What is a gene pool consists of all the genes within a?
all alleles for all genes in a population.
What is the essence of Darwin's theory of evolution?
Darwin's theory outlined natural selection, as one theory within the whole of evolution: those organisms that are better able to survive long enough to reproduce more often, will pass on the genes that result in their offspring surviving longer and reproducing more as well, resulting in that set of genes becoming more common in the population as time passes.
Why do common patterns of genetic control for development exist in animals?
They exist because all these genes have descended from the genes of common ancestors.
What is direct evidence of evolution?
direct evidence is the observation of evolution as it occurs. We have discovered novel genes conferring an advantage in an environment in which the ancestral population lacked those genes entirely. One example is flavobacterium that evolved nylonase enzymes. Antibiotic resistance is another example.
Do genes effect your health?
Yes. For example if cancer if very common in your family, you likely have genes that are more susceptible to it. That's why people say "its hereditary." It means its caused by your genes. If this is hereditary for you, you are more likely to die from cancer.

The collection of all the genes in a population is called?
Gene pool. All the alleles of all the genes of a population make up a gene pool.
Why do common patterns of genetics control development exist among animals?
They exist because all these genes have descended from the genes of common ancestors.
What are some variations in the zebras population?
In the zebra population there are variation in the stripes. Genes are responsible for variation in their stripes and there are no two zebras that are alike.
