1. Generally, production traits such as milk, fat, and protein yield are moderately heritable. While milk production traits are important, many other traits are of economic importance in dairy cattle breeding, including conformation, longevity, reproduction, health, and workability traits.

2. Would've surely practiced selective breeding via controlled mating... the three ways : Outcrossing , Line Breeding and Inbreeding can help in producing a herd of high yielding beef capital.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
