Question

a farmer harvests apples that are heavier than the average 5 kg weight for that variety. he plants the seeds from the harvest hoping that the next generation will produce even heavier apples. using the results found by galton, which statement is most likely true regarding the weight of the next generation?
the next generation will weigh twice as much as the parent generation, closer to 10 kg.
the next generation will weigh exactly the same as the parent generation.
the next generation will weigh less than the parent generation, closer to 5 kg.
the next generation will weigh less than the parent generation, closer to 2.5 kg.

Explanation:

Galton's work on regression to the mean indicates that extreme traits (like very heavy apples) tend to move closer to the average in subsequent generations. The average weight for the variety is 5 kg. So, the next generation of apples, which was bred from heavier - than - average apples, is likely to regress towards the mean.

Answer:

The next generation will weigh less than the parent generation, closer to 5 kg.
