WebAug 17, 2006 · Genetic diversity within a species helps fields to bloom. WebFor example, a high-yielding pea can be crossed with a mildew-resistant pea. The next generation plant is called the progeny. All progeny that are still mildew resistant are then crossed to their high-yielding parent. This is repeated a few more times, always crossing back to the high-yielding parent, and selecting the mildew-resistant progeny.

A measure of inbreeding of an individual A is the probability F(A) that both alleles in one locus are derived from the same allele in an ancestor. These two identical alleles that are both derived from a common ancestor are said to be identical by descent. This probability F(A) is called the "coefficient of inbreeding". Another useful measure that describes the extent to which two individuals are related (say indivi…

WebInbreeding, also called selfing, is the union of gametes derived from a single individual. In flowering plants, inbreeding may occur either within a single flower, known as autogamy (infrafloral selfing) or between flowers derived from one individual, known as geitonogamy. (The genetic product of autogamy is identical with that of geitonogamy.) Webplant breeding, application of genetic principles to produce plants that are more useful to humans.
