Conclusion Questions
1. Heredity is the passage of genetic instruction (Genotypes) from one generation to the next generation.
Choose five random Baby Bear traits (Phenotypes). Determine if the traits (phenotypes) were passed
on by Momma or Papa Bear’s genetic coding (genotypes). Circle the more dominate Bear.
