Genetic change is desirable in order to have an abundance of diversity within a population. This makes the population less susceptible to disease and illness, making the population more resilient.
Genetic drift is a product of random sampling. Like all forms of sampling or selection, variation within the sample set is required. Thus for genetic drift to occur genetic change (mutation) is required. However, it would be an error to call genetic drift a product of genetic change.
desirable changes are changes which we desire. Undesirable changes are changes which we dont desire. for example:souring of milk is a undesirable change and ripening of fruits is a desirable one.
Changes that are genetic
The change of genetic information within an organism is known as a genetic mutation. It may also be refereed to as a change in allele frequencies when populations are examined.
Bacteria cells have their own genetic material.
Are all changes desirable? Clearly not. Example: "lets change the notion of educating our children, to never educating them" All changes are not desirable. Then ask: Is any change always desirable? No. Should the prospect of change be desirable? Sometimes. The answer depends on perception, intention and outcome. The only truth with almost near certainty is to state the following: Change can be desirable.
Evolution is not a cause of genetic change: it is the effect of genetic change.
yes
selective breeding, cloning, and genetic engineering are three methods for developing organisms with desirable traits >,< i have a cold :]
to cross over which results in the genetic recombination

Selective Breeding
genetic drift....
genetic drift....
by planting desirable genes in the DNA through genetic engineering
Yes Both breeds have genetic traits desirable for meat and egg production.
desirable changes are changes which we desire. Undesirable changes are changes which we dont desire. for example:souring of milk is a undesirable change and ripening of fruits is a desirable one.
