- Student Notes 42. Marchigiana Size: large breed with heavy fine bone structure and strong feet and legs - cows weigh between 1.300 and 1 500: bulls weigh between 2,000 and 2,400 Usage: besides purebred use, the Marche is used as a terminal beef sire because the white hair color is a recessive trait and the calf is usually born the color of the dam popular cross is with the Angus breed high fertility, rapid growth rates, adaptability makes this breed popular in the United States and climate 43. Murray Grey Origin: Australia in the early 1900s, a light roan Shorthorn cow was crossed to several Angus, but all the new breed were gray- starting a semen was imnorted to the LU Inited States in 196a

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
