What is the common percentage of Brahman and British breeds in American cattle?

The correct answer reflects the commonly recognized proportion of Brahman and British breeds in American cattle, particularly in popular hybrid breeding practices. The designation of a "3/8, 5/8 cross" indicates that the animal is composed of 3 parts Brahman and 5 parts British breed, typically Hereford or Angus.

This hybridization aims to combine the heat tolerance, hardiness, and disease resistance of Brahman cattle with the desirable traits of British breeds, such as growth rate, meat quality, and reproductive efficiency. The resulting cross is favored in many regions of the United States due to its balance of traits that perform well in various environmental conditions, especially in southern climates.

Other options present different ratios that do not accurately reflect the prevalent breeding practices involving Brahman and British breeds, which is well-established at the 3/8 and 5/8 ratios. Thus, while they might represent other potential crossbreeding combinations, they do not align with the most commonly accepted ratios in the industry.
