In attached manuscript (breeding for better welfare :genetic goals for broiler chickens and their parents by Ms Dawkins and R layton ,2012 )identify 4 current trends that threatens genetic progress in animal breeding progress in the face of climate change challenges

New type of diseases, weak defense against disease, decrease in product quality and more production of the product.

Explanation:

New type of diseases, weak defense against disease, decrease in product quality and more production of the product are four trends that threatens genetic progress in animal breeding in the face of climate change challenges. Due to new type of diseases the genetic makeup of organism is unable to defend itself due to weak defense mechanism that leads to decrease in quality of that animal.

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.

explanation:

it will increase due to the time span
