For example, a ...Despite the upward trend in crop yields in the US and other parts of the world, rising human and animal populations will pose a greater demand for more to be produced per unit of land. For example, a plant breeding goal may have two objectives, 1) selection and fixation of desirable genes at a set of loci controlling a trait of interest, and 2) keeping genetic variability at the remaining loci to retain adaptability.

The Phenotype can be determined in column I, by adding the following command in field I4: “=SUM(C4:F4)”. This will add for DH genotype 1 the values in fields C4 to F4, which according to the model adds up to the Phenotype of this genotype.

(1999b) revealed that the four-stage selection strategy is the most efficient procedure in MABC, the success of MABC also relies on several factors, including distance between markers and the target gene, the number of target genes to be backcrossed, the number of individuals that can be evaluated and the genetic background of the recurrent parent, types of molecular markers and instrumentation for marker analysis.

(Assume that “parent” means either a random plant or line from a population.) Thus, X, the parent value, is the independent variable, and Y, the progeny value, is the response or dependent variable.
