Blood types and transfusions are explained in reading passages at the top of the worksheet. A chart of blood type compatibility is also provided. Biology students answer comprehension questions and then exercise critical-thinking skills...

This multiple-choice and short-answer quiz covers chromosomes, genetic disorders, and more. The multiple choice section could work as a pretest, as well.

Can your young biologists interpret population graphs, match macroevolution patterns and descriptions, and answer multiple choice questions about evolution? Find out with a comprehensive three-page quiz covering some specific examples of...

In this theory of evolution worksheet, students review vocabulary words associated with evolution including the different types of evolution patters. This worksheet has 5 true or false and 5 matching questions.

In this science worksheet, students find the answers to various types of heredity problems. They use the sheet to set goals for completing the unit.

Students solve a crime by matching a suspect's blood type to physical evidence collected at the crime scene. In this forensic science lesson, students identify the different blood types. They explain how blood tests work.

Students identify the different kinds of blood. In this biology lesson, students investigate the antigens, agglutinins and Rh factor using their own blood. They use Punnett squares to predict blood type of offspring.

Students analyze gels to determine parentage in this lesson about scientific evidence, investigation, and DNA concepts. The lesson includes a pre-activity worksheet, a final individual assessment, and student handouts for in-class...

Students slve a case of unclear heredity using three lines of evidence and knowledge gained from the lesson in this biology lesson about Mendelian inheritance. The lesson includes handouts and a question sheet for final, individual...

In the real world, genes often come in many versions (alleles). Alleles aren't always fully dominant or recessive to one another, but may instead display codominance or incomplete dominance.

Article reviews Mendel's basic model of inheritance then provides an overview of variations on Mendel's laws, including multiple alleles, incomplete dominance, co-dominance, pleiotropy, lethal alleles, sex linkage, genetic interactions,...

A tutorial reviews polygenic and multiple alleles, Punnett Square, sex-linked trait, and inheritance patterns. Follow the slides to ensure comprehension of inheritance.

A multiple-choice quiz on genetics terms and concepts.

A multiple-choice quiz on the mechanisms of evolution.
