Life History Variation Traits and Strategies A. High r Value 1. Produces a few, large offspring B. Single Breeding Event 2. Adaptation to high reproductive fitness C. Multiple Breeding Events 3. Breeds many times during lifetime D. Large Offspring 4. Breeds once in lifetime
Options
- AA - 3, B - 1, C - 2, D - 4
- BA - 2, B - 4, C - 3, D - 1
- CA - 1, B - 3, C - 2, D - 4
- DA - 4, B - 2, C - 1, D - 3
Correct answer
B. A - 2, B - 4, C - 3, D - 1
Step-by-step solution
A high r value indicates adaptation to high reproductive fitness. Organisms that breed only once in their lifetime (e.g., Pacific salmon) follow a single breeding event strategy, while those breeding multiple times (e.g., birds and mammals) have multiple breeding events. Producing large offspring is a trait of certain organisms.
