Fig. 2. The performance of the Mapping Start Only (MSO) and three versions of the Mapping As You Go approach averaged across all genetic models considered in the experiment. (a) The performance is shown in terms of trait value normalized between 0 and 100%. (b) The response shown in (a) is represented as the difference in response between a given breeding strategy and the MSO method. Positive values indicate the breeding strategy had a higher response than the MSO method, and negative values indicate the breeding strategy had a lower response than the MSO method. The performance differences are expressed in terms of normalized trait value.
