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 and make conclusions concerning the genotype relevant to a visible phenotype. This is an excellent Lab-Aid to correlate heredity with environment influences.
