Welcome to my shop! I love being able to help other teachers during the year when they have so many things on their plate. I have taught both high school and junior high school science. I was also a scientist for a few years before I decided to teach. It made teaching very interesting and the students loved the stories. I hope I have a little something for you all!

I am able to customize vocabulary cards for any topic. Please let me know if you are looking for something specific. Test, Review Questions, and Answer Keys The test is multiple choice, Punnett Square problems, and Pedigree questions. This test is designed to take about 45 minutes to an hour. The following are the review questions that are covered on the test. These are not exact test questions, just topics that cover the material: What is the difference in phenotypes and genotypes? What is the difference in dominant and recessive alleles? How are genes expressed? What is heredity? What is a mutation? Where do you find the genetic material that is passed from parent to offspring What are alleles? Who is known for being the ‘Father of Genetics’? What is a gene? Punnett Square practice In cats, short hair(S) is dominant over long hair(s). A homozygous recessive individual and a homozygous dominant individual are crossed. Homozygous recessive parent genotype? Homozygous dominant parent genotype? Probability of short hair offspring? Probability of long hair offspring? A colorblind man and his carrier wife have children. Male parent genotype? Female parent genotype? Probability of colorblind offspring? Probability of carrier offspring? Incomplete dominance: a red flower crossed with a white flower. What are the genotypes of the parents? What are the genotypes of the offspring? What are the phenotypes of the offspring? What are the probabilities of the phenotypes of the offspring? Co-dominance: a red flower crossed with a white flower. What are the genotypes of the parents? What are the genotypes of the offspring? What are the phenotypes of the offspring? What are the probabilities of the phenotypes of the offspring? Single gene with multiple alleles—A type AB blood man and a homozygous type B blood female have children. What is the probability of blood type A offspring? What is the probability of blood type B offspring? What is the probability of blood type AB offspring? What is the probability of blood type O offspring? Students will use a pedigree to answer the following: Individuals B, D, I, and N are colorblind. Correctly shade those 4 individuals in the pedigree. Individuals C, G, and J are carriers. Correctly shade those 3 individuals in the pedigree. Explain why individual I and J, although they are sisters, do not share the colorblindness phenotype.
