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
