"Ward's Phenomena"

One each of foliose, crustose, and fruticose lichen. The foliose and crustose lichens are any of a wide variety of species; the fruticose lichen is either cladonia or reindeer moss. All samples are field-collected and come in a 4 oz. labeled jar.

Deuteromycete. Produces penicillin. Incubation temperature 25°C. Malt extract agar growth medium.

Supplied as tube cultures. Comes with culture and handling instructions, as well as the manual Working with Fungi.

Eight strains: a1 (HAO), α1 (HBO), a2 (HAR), α2 (HBR), a3 (HAT), α3 (HBT), a4 (HART), α4 (HBRT).

Classic experiment to demonstrate crossing over.

Mold structures

A quick and colorful demonstration of Mendel’s Law of Segregation.

Mendel’s Law of Independent Assortment made easy.

Observe the differences between common mold types

Yeast strains are ideal for genetic study because they are easy to grow and maintain, their life cycle is complete in approximately one week, and you can arrest different stages of the life cycle by growing it on different types of media.

Penicillium notatum is a deuteromycete that produces penicillin. It is available in normal and high-yield strains.

Use Sordaria fimicola to allow students to visualize the results of crossing over during cell division.
