The process of organisms fighting for mates food and living space is called competition.

Explanation:

Ecological interactions of organisms include adaptations, interdependence with each other and competition.

Although there is an abundance of natural resources for food and space, due to ever increasing demands and evolutionary and environmental changes, organisms constantly compete with each other for resources like food and space.  

Organisms fight or compete with each other for food, shelter, mate, sunlight etc.

The autotrophs need to compete with each other for resources needed for photosynthesis like water, carbon dioxide, and other nutrients and minerals present in the soil. Similarly other consumers compete with each other for food. This competition may be interspecific (between two or many species) or intraspecific (within the same species).

Biodiversity helps to balance the ecological systems and avoid this competition between organisms.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
