Recall that a farmer has a herd of cattle with an average weight of 1,000 pounds. He bred a group of his heaviest cattle, which have an average weight of 1,800 pounds. The offspring had an average weight of 1,700 pounds.

Calculate the heritability for this trait, and explain whether the trait is highly heritable.

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.

Im gonna fail 7th grade selective breeding 1. creates offspring which are genetically identical to the parent 2. is the process of breeding only organisms with desirable traits 3. involves the removal of the nucleus of a cell 4. combines traits from organisms of different species
