Axolotl Pigmentation

Love axolotls? Use this model to investigate the inheritance of axolotl pigmentation.

Run the model

Axolotl Pigmentary System

Three pigment cell types are found in adult axolotl skin, including melanophores, xanthophores, and iridophores. The types and amount of these cells determine axolotl pigment phenotypes.

Grades: 6-12, College introductory biology
NGSS Standards: MS-LS3; HS-LS3

Run the model

Probabilities in Genetics

This model allows students to explore the impact of population size on the distribution of the offspring phenotype proportions.

Grades: 6-12, College introductory biology
NGSS Standards: MS-LS3; HS-LS3

Run the model

Genetic Linkage

Investigate the genetic linkage, including both X-linkage and autosomal linkage. This model includes the common examples mentioned in textbooks.

Grades: 6-12, College introductory biology
NGSS Standards: MS-LS3; HS-LS3

Run the model

Genetic Linkage Analysis in Drosophila

This model includes the traits that are not often mentioned in the textbook--bar eyes, yellow body color, and dumpy wings in fruit flies (Drosophila melanogaster), so teachers may use it to extend students’ understanding after teaching the common examples (e.g., white-eyed).

Grades: 6-12, College introductory biology
NGSS Standards: MS-LS3; HS-LS3
