Gene Action/Mutation Worksheet

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...

Fill- in-the-blank, labeling, and short answer questions make up this well-written cell division worksheet. Neat diagrams of chromosomes and dividing cells are included. Junior biologists show what they know about reproduction, meiosis,...

Ms. Strohfeldt did not omit anything when she designed this comprehensive lesson plan on DNA mutation and sex-linked traits. Begin with a pretest as an anticipatory set. Read a case history of the Clark family and the occurrence of...

Here is yet another variation of the classic activity in which lab groups use different tools to imitate different bird beaks as a demonstration of one of the factors in natural selection. What makes this one unique is that it is on a...

In this biology worksheet, students review and answer different questions based upon the molecules of DNA and RNA. They look at the specific protein order of the DNA strand and its synthesis.

Geneticists manipulate Punnett squares to determine the patterns of dominant and recessive gene influence on first and second generations of humans and plants. The technology-based lesson plan employs a variety of media for exploring...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

Dive down to Bikini Bottom for a fantastic lesson on heredity! High school scientists make phenotype predictions for various characters based on given dominant and recessive traits. Use the PowerPoint here to review this concept before...

Students review terms related to DNA structure and function. They complete a variety of worksheets in small groups or in pairs reflecting the unit's concepts regarding DNA. They submit their worksheets for grading.
