Hybrids and Purebreds for Real Agriculture Biology

 Question of the Day:  What is selective breeding used for?  Objective:  Today I will use my knowledge of selective breeding principles to simulate hybridization and inbreeding.

Today’s Activity  2 scenarios:  This is the only buck…  Given specific traits to select for…  2 does to choose from…  Which doe will you choose?

Vocabulary  Buck: An intact mature male goat  The _______ smelled terrible because it was breeding season.  Doe: A mature female goat  My _______ is getting ready to kid.

Dairy Goats  Main Use:  Milk production  Main Characteristics:  Feminine  Refined  Capacious  Breeds:  Toggenburg  Alpine  Nubian  Saanan  Oberhasli  LaMancha

 Main Use:  Meat production  Main Characteristics:  Thick muscling  Big boned  Good fat cover  Breeds:  Boer Goat  Spanish Goat  Tennessee Goat Meat Goats

Meat Goat or Dairy Goat?

Your Task:  Choose a doe to breed to this buck for each of the scenarios, and explain your choice.  Scenario 1: You want the offspring to only produce meat.  Scenario 2: You want the offspring to produce quality milk and meat. The white does will be #1, the grayish does will be #2

What Were we Doing?  Scenerio 2:  Hybridization:  Crossing organisms than have different traits to bring together the best of both organisms.  Scenerio 1:  Inbreeding:  Continued breeding of individuals with similar characteristics.
