Hybrids and Purebreds for RealAgriculture 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

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.
