Classroom Activities: Pedigree Analysis Activity
Trace a genetic trait through an entire pedigree. A class activity provides pupils with an opportunity to explore a pedigree tree displaying a specific trait. They draw conclusions from the display and provide recommendations based on...

Genetics
Trace simple genetic patterns of inheritance through a small population. Your students create a family pedigree that traces a genetic condition through several generations.

Autosomal Pedigrees Worksheet
Three autosomal pedigrees are printed on this assignment. Biology scholars read them and determine the phenotypes for several individuals and find which ones inherit different genetic disorders. This fundamental skill can be reinforced...

Genetics
A handout on genetic inheritance begins with a reading on alleles and how they can result in albinism. Junior geneticists learn to complete Punnett squares and participate in a coin toss simulation of allele pairing. They also learn...

Genetics Practice 4: Pedigrees
Four two-generation pedigrees are presented in this genetics worksheet. For each, five questions are asked: Is the trait autosomal recessive, autosomal dominant, x-linked recessive, x-linked dominant, or y-linked dominant? Whenever...

Recombination and Pedigrees
Biology aces answer four questions about genetic recombination and nine questions about pedigrees. This worksheet is very focused on these two topics. Most of the pedigree questions relate to the genetic disorders, Alkaptonuria and...

Heredity: Traits, Genes, Alleles
If you knew people would pay extra for a bald dragon, could you pick which parents you should breed in order to get the highest number? The unit examines heredity and genetics through breeding dragons, mice, dogs, and tries to figure...

Unit 3: Genetic Variation
What happens when genes change? Junior genetic investigators examine the effects of mutation in the third unit of a four-part Biotechnology series. Individuals discover the types of mutations through a series of PowerPoints, then partner...

Pedigree Charts
Students explain how offspring inherit traits from their parents. In this biology lesson, students investigate the genes for nicotine addiction using an interactive website. They construct a fictional pedigree using their chosen...

Take Home Lab: What Are Some Traits in Your Family?
Young scholars use this following the study of pedigree designs and human genetics. Four pedigree designs are prepared of your (student's) family's genetics. They construct the pedigree representing two, three, or four generations.

Family Traits
Young scholars investigate the study of pedigree designs and human genetics. They construct the pedigree representing two, three, or four generations. They investigate their family members' traits for ear lobe attachment, tongue...

Mendelian Genetics, Probability, Pedigree, and Chi-Square Statistics
People with the sickle cell trait, but not sickle cell disease, find natural protection against malaria. Scholars consider various combinations of genotypes and environmental factors to determine if children might have sickle cell...

Pedigrees and the Inheritance of Lactose Intolerance
What, exactly, causes lactose intolerance? Scholars view a video describing a Finnish study that determined why some people are tolerant while others are intolerant. They then use the data from the study to reenact the experiment and...

Family Pedigrees
High schoolers work as a class to first construct a pedigree of a popular singer, showcasing the singing gene being passed down through the generations. Students then make their own family pedigree and follow two traits through their...

Real Family Genetics
Students research genetic disease and mutation causing traits in family pedigrees simulated in a class activity. Students are each assigned a genetic trait and a "spouse" and must conduct research on their traits and the probability of...

Mendelian Inheritance of Human Traits
In this Mendelian inheritance worksheet, students will use a pedigree to complete 4 short answer questions about recessive and dominant traits. Then students will create a Punnett square. Finally, students will match 5 genetic disorders...

Variation and Heredity
Junior geneticists tally eye color and height in their lab groups. They examine certain traits in soybean and corn seedlings. For each activity, they gather data and learn about continuous and discontinuous genetic variation. In another...
Curated OER
Human Genetics
In this biology learning exercise, 9th graders describe whether the father or mother is affected by a sex-linked disorder and why. Then they name two genetic disorders that are caused by a recessive allele on the X-chromosome. Students...

Adaptations to Niches and Habitats
Life science learners measure and record traits of seeds, leaves, and their own hands and then graph the data to find a continous distribution curve. They compare and color diagrams of seven different animals' forelimbs (not included),...

Pedigrees
Students examine various inheritance patterns using pedigrees. In groups, they predict what might happen to the offspring of a woman with normal vision and carries the recessive allele gene. They determine the genotypes of the man and...

Patterns of Heredity
A family tree of dogs guides learners through this activity, in which students analyze the pedigree. With a key describing the genetic attributes (tall dominant, short recessive, or male/female), learners complete five questions about...

How Does a Pedigree Help Us to Trace a Trait That is Inherited?
Students analyze genetic patterns. In this pedigree lesson, students determine dominant or recessive inheritance. They construct a human pedigree from genetic information.
Curated OER
Human Genetics
In this biology worksheet, 9th graders create a Punnett square to show the possible offspring of a carrier female and a normal male for color blindness. Then they draw a pedigree for the family and indicate whether the daughter is...

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