You are conducting an observational study of the effect of directional selection on thesize of the wattle in the New Zealand wattlebirds. In an initial study, you measure themid-parent/mid-offspring regression of this trait (below) and found the slope of theregression line to be 0.35. You have a population of wattlebirds with an averagewattle size of 28 cm2. You want to breed for decreased wattle size the wattlebirds sothat the mean wattle size for the next generation is 21 cm2. To do so, you will need totake advantage of the breeder’s equation (R = h2 x S). (Lip; you may or may not beable to complete these questions in order). Find/calculate the value for “R” for the above example: Find/calculate the value for “hz” for the above example: Find/calculate the value for “S” for the above example In order to breed for this decreased trait size, you would need to artificially select for breeders with what average wattle size?
