Heredity and Environment

Kit #77
$108.10

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. Students also stimulate shoot production and examine the relationship of the dominant gene (chlorophyll production) to the recessive gene. Finally, students make conclusions concerning the genotype relevant to a visible phenotype.
