Heredity and Environment

kit #77

By germinating hybrid tobacco seeds first in darkness and then in light, students make interesting observations using this challenging kit.

• Students set up controlled experiments that provide mathematical data to test their theoretical genetic hypothesis about heredity and the factors determined by the environment.
• They see how a recessive trait becomes evident.
• Students also germinate the hybrid tobacco seeds with one normal and one albino gene
• Stimulate shoot production
• Examine the relationship of the dominant gene (chlorophyll production) to the recessive gene
• Make conclusions concerning the genotype relevant to a visible phenotype.

This is an excellent Lab-Aid to correlate heredity with environment influences.

Accommodates one class with 15 groups of two students.


  • Discover which is more important: Heredity or Environment
  • Controlled experiment provides mathematical data to test hypotheses
  • Discover how a recessive trait becomes evident
  • Examine the relationship of a dominant gene to the recessive gene and draw conclusion concerning the genotype relevant to a visible phenotype
