Students assess some common inherited traits which are easily observable and note their phenotype for the trait. Students compare their phenotypes to those of their parents and attempt to describe the pattern and manor of inheritance.

Learners perform an experiment in which they extract DNA samples from hair samples. They follow a set procedure to extract the DNA and complete summary questions.

Students analyze different types of hemoglobin. They use the technique of agarose gel electrophoresis to separate human hemoglobin molecules according to their electrical charge, size, and/or shape. Students relate the migration of...

Students explore the concept of extinction by studying dinosaurs. In this dinosaur lesson, students distinguish between extinct creatures and those that still exist.

Tell case study story of EMS-induced chlorophyll polka-dots in C-ferns. You will need to be familiar with the experiment, as there are some slides that have only photos, no text and no presenter's notes. By using this presentation,...

In this biology worksheet, 9th graders determine whether it is possible for two alleles to produce four genotypes. Then they state how many alleles there are for blood type. Students also determine which blood type is inherited by...

In this genetics instructional activity, students use Punnett squares to determine the possible genotypes of offspring based on blood type. This instructional activity has 6 problems to solve.

Students randomly select jelly beans that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from...

Ever been told you have your father's eyes? How did it happen? Young biologists get a hands-on experience in meiotic gene expression with a fun pairs-based activity. Participants use pipe cleaner chromosomes with trait beads to make...

Students study the blood characteristics of a number of distinct racial/ethnic groups. They build skills in observation, information gathering and processing. Students experiences strongly reflect the nature and intent of the current...

Students come to understand that in sexually reproducing organisms, such as humans, typically half of the genes come from each parent. Students examine a fictional pedigree and determine which gene is responsible for a given trait. The...

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 view a video on DNA. They discuss mitosis, meiosis and fertilization. They use strips of paper to simulate fertilization and analyze the genotype and phenotype of the combined chromosomes.

Students explore neurological disorders. They examine the presence and absence of discernible genes. Students describe neruological diseases and draw faces of affected persons. They play a human neurology disorders learning game.

Pupils analyze the causes of cancer from a genetic standpoint. They explain the increase in cancer with age and create a hypothesis for cancer development. They use the laws of probability as well.

Tenth graders work on a project about cellular biology and genetics. In this biology lesson, 10th graders research about the assigned human body system and genetic disorders that affect it. They create a multimedia presentation and...

Your genetics juniors will benefit from this lesson. They read an article about a Special Olympics winner and then discuss how life might be for someone who suffers from Down Syndrome.

Students investigate variation in the beta globin gene by identifying base changes that do and do not alter function, and by using several Internet-based resources to consider the significance in different environments of the base...

Students describe some aspects of known genetic defects on the human neurological condition. They participate in a variety of exercises including drawings, games, and analogies.

Students explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...

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.

Young scholars explore plant DNA.

This site has the defintion, illustrations, and an audio explanation of the term.

For a concise summary of human blood types, this is a great resource. Discussion includes the topics of genotype, phenotype and agglutinins. There is also a nice pictorial table that summarizes the three blood types.
