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.
Given the phenotypes of offspring in mice, flowers, and human blood type, genetics pupils practice determining the genotypes of the parents. Four short answer questions follow. The entire assignment will require learners to put on their thinking caps! Keep this on file as a possible homework assignment for your biology class.
For 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 traits. Then students will answer 4 short answer questions about environmental influences on gene expression.
High schoolers explore DNA microarrays. In this genetics lesson plan, students model DNA microarrays that are used by scientists. High schoolers work to determine levels of breast cancer genes in patients. They will determine the treatment required based on their findings.
The metaphors used here to describe the "cut and paste" procedures for genetic engineering will really help your biologists in their understanding of restriction enzymes and DNA. The uses of genes that are isolated and incorporated into plasmids are discussed and will help your students learn the real life opportunities and application of biotechnology.
Eighth graders are able to define meiosis. They are able to compare and contrast meiosis and mitosis. Students are able to state the phases of meiosis. They complete a K-W-L chart on meiosis and mitosis. Students talk about meiosis and sexual reproduction and give definitions.
Students predict possible phenotypic and genotypic outcomes for avariety of common plant hybrids. They review and explain the characteristics of dominant and recessive traits and explore Mendelian genetics. Students plot the possible possible outcomes of a designated set of plant hybrid offspring.
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 genetic information for individuals is depicted as a jigsaw puzzle. Terms that students encounter include gene; chromosome; DNA; pedigree; genotype; phenotype; dominant; and recessive.
