In this inheritance patterns worksheet, students create a visual of a Zork using chromosome strips to represent alleles from the father and the mother to determine the traits in the offspring. Kids translate the genotype to the phenotype and compare their Zork to others in the class. Students explain the differences even though the parents of all the Zorks are the same.
Students investigate genetic inheritance using pipe cleaners and beads to represent chromosomes and genes. In this inheritance lesson plan, students are given a bag of their "chromosomes" and "genes" to simulate the inheritance of dominant and recessive traits as well as sex-linked traits. They produce offspring by doing crosses and show punnet squares of their offspring. They analyze their data by answering 6 questions.
Young scholars model traits on genes using colored paper and tongue depressors to represent chromosomes. For this heredity lesson plan, students use their "chromosome sticks" to understand chromosome pairs, genes, dominant traits, recessive traits, heterozygous, genotypes and phenotypes. Young scholars create different gene combinations using their chromosome sticks.
Deepen understanding of cell division with this resource. Young scientists read short paragraphs about the different stages of the cell cycle and use this information to answer a series of basic short answer questions and label several diagrams. This is an extensive series of paragraphs and questions that are based mostly on identification. You could give this out as a packet.
AP biology course-takers peer into the workings of inheritance with this worksheet. They examine the Chromosomal Theory of Inheritance, Morgan's fruit fly experimentation, and sex-linked genetic traits. Vocabulary definitions and critical-thinking questions are included in this four-page comprehensive assignment.
Advanced biology masters take a close look at DNA and the scientists who contributed to our understanding of this complex and powerful molecule. They answer 21 questions about DNA structure, replication, and repair. This can be used as a note-taking page, a reading guide (if your textbook covers the same material), or a review assignment.
In this chromosomes worksheet, students compare the chromosome numbers for different animals and complete 2 graphic organizers with this information. Students compare autosomes and sex chromosomes. This worksheet has 3 graphic organizers, 6 fill in the blank, and 5 short answer questions.
Students comprehend that karyotyping is a process in which chromosomes are cut from an enlarged picture and arranged in decreasing order of size. The cells to be viewed are first chemically treated to increase the number of dividing white blood cells and then treated with colchicines to stop mitotic division during anaphase. Lastly, the cells are burst open, stained and fixed. The slide is examined for well spread chromosomes, photographed, and karyotyped.
