Lab-Aids™ Heredity and Environment
Discover which is more important: Heredity or Environment. Controlled experiment provides mathematical data to test hypotheses, discover how a recessive trait becomes evident and examine the relationship of a dominant gene to the recessive gene and draw conclusion concerning the genotype relevant to a visible phenotype.
Supplier: Lab-Aids™ 77
Includes: Teacher's guide; 30 student worksheets and guides with data charts; 60 germinating papers; 15 germinating dishes, clear plastic, two-section; 15 germinating dishes, opaque plastic, two-section; 1 albino tobacco seeds, vial
DescriptionBy 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. Accommodates 1 class with 15 groups of 2 students.
