* A strawberry farmer determines that the average weight of individual strawberries produced by plants in his garden is 2 g. He selects the 10 plants that produce the largest strawberries; the average weight of strawberries produced by these selected plants is 6 g. He interbreeds these selected plants. The progeny of these selected plants produce strawberries that weigh an average of 5 g. If the farmer were to select plants that produce strawberries with an average weight of 4 g, what would be the predicted weight of strawberries produced by the progeny of those selected plants

R = Alteration among mean initial population and mean offspring of designated parents

S = Assortment alteration among the mean initial population and the mean designated parents

if the designated selected plants averaged then S would be and

.

Thus, the average weight of strawberries would be

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
