In this biology worksheet, 9th graders name two forms of the trait for seed shape observed by Mendel. Then they determine the percentage of the possible types of offspring that have the same genotype as the parents. Students also explain...

In this genetics worksheet, learners 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...

Explore the science behind Earth's amazing diversity of life with this lesson on genetics. Looking at specific traits in piebald deer, carnations, and roan cattle, young scientists use Punnett...

Students research the population of Bengal tigers and their existence as either dominant or recessive. They explore the presence of fur on these tigers and its lethal combinations. Determinating the effect of random mating in a...

Students research genetic adaptations. In this chromosome instructional activity, students investigate dominant and recessive genes using spiders indigenous to Hawaii. Students create Punnett squares to determine the probability of...

In this worksheet, students will answer 4 fill in the blank statements about Mendelian inheritance and meiosis. Then students will use Punnett squares to answer three short answer questions. Students will match 8 genetics vocabulary...

In this heredity worksheet, students will create 3 Punnett squares to determine the genotype and phenotype of the offspring from specific breedings. Then students will answer 7 true or false questions based on chromosomes and sex-linked...

In this biology learning exercise, 9th graders identify and locate various vocabulary terms related to the study of genes. There are 18 biology terms located in the word search.

For this genetics worksheet, learners are given two coins that they mark with a "F" and a "M" to represent parents. They flip the coins to determine the genotype and phenotype of the offspring for twelve traits. They also use the coin to...

In this biology instructional activity, students identify and locate various vocabulary terms related to genetics. There are 15 biology terms located in the word search.

In this genetic worksheet, students will complete 4 fill in the blank questions about selective breeding and determining genotypes. Then students will use a Punnett square to determine the genotype for two different breeding situations.

Students study genetic traits using popsicle sticks as chromosomes. For this biology lesson, students explain how traits are inherited from parents. They differentiate dominant and recessive genes.

Students explore genetic terms, the Law of Dominance and the contributions of Gregor Mendel. After discussing Mendel's lab and his pea plants students observe examples of a phenotype chart. Afterward, they conduct their own lab to...

Students revie the Law of Independent Assortment and Law of Dominance. They practice Punnet squares and predicting genetic outcomes and identify factors that influence heredity.

Students determine their inherited characteristics from their parents. In this biology lesson, students study the life of Mendel using an interactive website. They differentiate dominant and recessive characteristics.

Excellent examples and clear diagrams in this PowerPoint will help you explain the genetics of alleles and the combinations of hybrid crosses. A high school class would appreciate having this student copy of the PowerPoint as the images...

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

Follow fruit fly genetics with this probability activity. Biology scholars analyze the alleles of Bugsy, Daisy, Dino, and Lulu, considering traits for antennae, wing type, and eye color. They solve Punnett squares to determine the...

How often do you find a science worksheet that comes with separate teacher's instructions? Here is one of those rare instances. Goals and objectives, materials, and evaluation guidelines precede the actual assignment. Biology leaners...

The Hardy-Weinberg principle is the focus of this concise slideshow.  Some vocabulary definitions are given on the first 2 slides, and the rest are given over to examples of the Hardy-Weinberg theorem. Calculations of the H-W...

The five agents of evolutionary change are reviewed in this slideshow. Definitions of common terms involved with populations and equilibrium are given, and there are some presentations of Hardy Weinberg equations for common examples of...

If you need a summary of all aspects of Mendelian genetics then this  slideshow is for you. The information included is essential for complete understanding of crosses, genotypes, phenotypes, and heredity.

Six genetics problems are to be solved by junior geneticists. Empty Punnett squares are provided for them to plant the parents' alleles and determine the genotype, phenotype, and frequency of offspring. All of the problems involve actual...

A three-page quiz about genetics, which includes Punnett squares, blood types, questions about Mendel and his contributions, and vocabulary comprehension. Use this for a study guide, a pretest/post-test, or a note-taking worksheet in...
