New! Finding Nemo Genetics: Incomplete Dominance
Consider the genetics of the coral in which Nemo and his father live. Marine geneticists practice using Punnett squares to determine phenotypes and genotypes in incomplete dominance crosses. After solving three problems about the offspring of the coral, students then solve four problems about the colored pearls produced by oysters. This attractive and engaging worksheet is an ideal homework assignment for your biology class.
Beyond Mendel: Incomplete Dominance and Codominance
What happens when two cats collide? It depends on whether they exhibit codominance or incomplete dominance! Genetics learners are briefly introduced to the these two concepts and are given a scenario to solve. This handout can be used in your biology lesson as you are introducing dominance that differs from Mendel's original observations.
In this biology activity, students use the information given about genetics and Sponge Bob to complete each section of the sheet. They identify and explain incomplete dominance and use it to help them complete the questions that follow.
Incomplete Dominant and Codominant Traits Worksheet
A two-page worksheet provides seven Punnett squares for practice in determining genotypes and phenotypes. Each is an example of incomplete dominance or codominance. After your bright biologists have mastered Punnett squares, this will take them to the next step. Assign it as homework or use it as an assessment after some time have been invested in these genetics concepts.
A girl without freckles is like a night without stars! On this worksheet, junior geneticists determine how many of the offspring of a freckle-faced father and a freckelless mother. They also write out answers to questions about Mendel's experiments, incomplete dominance, and codominance. This handout provides a well-rounded review of genetics concepts. Add it to your collection of choice homework assignments.
Genetics of Parenthood
Students participate in an activity where they flip coins to determine which allele they pass on to the F1 generation and draw the resulting child's face. They identify several inheritance patterns including dominant, recessive, incomplete dominance, polygenic, sex-linked, and epitasis.
Learners explore incomplete dominance inheritance by learning about the survivors of the Black Death and completing Punnett Squares.
Incomplete dominance, Codominance, Multiple Alleles
High schoolers explore the principles of incomplete dominance and codominance in genes. They apply genetic previously discussed genetic principles to determine solutions to inheritance problems including multiple alleles, incomplete dominance and codominance.
Fun With Genetics!
Students use the internet to research a specific type of genetic problem they have read about. In groups, they use their textbook to analyze the characteristics of new vocabulary and concepts. They develop a solution to the genetics problem and share their information with younger students.
Punnett Square Fun
The topics in the previous video about dominant and recessive traits are continued here as Sal Khan explains incomplete dominance, the randomness of genotypes and phenotypes, and covers how to calculate probabilities using Punnett squares for one or multiple traits.
In this basics of genetics activity, high schoolers review the concepts of genetic inheritance by writing the alleles for genetic traits inherited in offspring. They identify dominant and recessive traits given allele pairs, answer five questions about genetic crosses, practicing monohybrid and dihybrid crosses, and complete sex-linked and incomplete dominance crosses.
In this genetics worksheet, high schoolers answer a variety of questions about genotypes, phenotypes, genetic inheritance, and traits. They solve for the probability of genotypes and phenotypes of offspring by completing monohybrid and dihybrid crosses. They answer questions about sex linked traits, incomplete dominance and pedigree charts.
Students study Mendelian Law of Experiments. In this biology lesson, students identify the different traits of crossing Mendel's Pea plant. They discuss the law of segregation as it relates to crossing.
Human Genetic Disorder Probabilities
In this genetic disorders worksheet, students complete punnett squares for six different human genetic disorders. They predict the outcome of the offspring including the phenotypes and genotypes of each.
Genetics Practice: Beyond the Basics
What do you get when you cross a purple with a white? Genetics geniuses figure it out with a Punnett square. On this assignment, they must solve crosses for incomplete dominance, codominance, lethal dominance, and sex-linked genes. It is a rare worksheet as most Punnett square practice pages involve only simple crosses. You will want to include this in your arsenal of genetics homework assignments.
Patterns of Heredity
Students describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then interpret testcrosses and pedigrees charts.
The Genetics of Parenthood
Learners draws the child's face and compares "mother's" and "father's" perception of characteristics. One student draws the child's face; partner writes a biography of the child at age 30- what is the child like, what have they accomplished, what are their dreams.... Students discuss how they feel about their parents and their perceptions of parenthood.
Complete Dominance Traits
In this lesson, 10th graders produces a different phenotype since the dominance is incomplete. Both parents have a spotted nose. After student have determined traits, they create drawings. Students chart thier respones in the graphich organzier.
Using Blood Tests to Identify Babies and Criminals
Young scholars 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.
Dragon Genetics Lab-Principles of Mendelian Genetics
Students study genetic traits using popsicle sticks as chromosomes. In this biology lesson, students explain how traits are inherited from parents. They differentiate dominant and recessive genes.
