Comparing mitosis and meiosis

Comparison of the processes of mitosis and meiosis. Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell. Mitosis involves one cell division, whereas meiosis involves two cell divisions.

The Genetic Basis of Inheritance and Variation
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

The topic of this video module is genetic basis for variation among humans. The main learning objective is that students will learn the genetic mechanisms that cause variation among humans (parents and children, brothers and sisters) and how to calculate the probability that two individuals will have an identical genetic makeup. This module does not require many prerequisites, only a general knowledge of DNA as the genetic material, as well as a knowledge of meiosis.

This course discusses the principles of genetics with application to the study of biological function at the level of molecules, cells, and multicellular organisms, including humans. The topics include: structure and function of genes, chromosomes and genomes, biological variation resulting from recombination, mutation, and selection, population genetics, use of genetic methods to analyze protein function, gene regulation and inherited disease.

Rating
0.0 stars

The Geniverse software is being developed as part of a five-year research project funded by the National Science Foundation. Still in its early stages, a Beta version of the software is currently being piloted in six schools throughout New England. We invite you to try the current Beta version, keeping in mind that you may encounter errors or pages that are not fully functional. If you encounter any problem, it may help to refresh or reload the web page.

Students randomly select jelly beans (or other candy) that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple's offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the "couples" in the class. In particular, they look to see if there are cases where parents and offspring share the exact same genotype and/or phenotype, and consider how the results would differ if they repeated the simulation using more than four traits.

How can we Design Cattle to Better Meet Human Needs?

In this high school Storyline unit on genetics and heredity, students are introduced to ‘SuperCows’. As they explore the vast variety of cattle breeds, students discover that cattle are specialized for different purposes and while similar, the ‘SuperCows’ are clearly unique. Students wonder what caused this diversity and specificity which leads to investigations about the role of inheritance, DNA and proteins.

Meiosis and Fertilization – Understanding How Genes Are Inherited
Rating
0.0 stars

Students use model chromosomes and answer analysis and discussion questions to learn about meiosis and fertilization. As they model meiosis and fertilization, students follow the alleles of a human gene from the parents' body cells through gametes to zygotes; thus, students learn how a person inherits one copy of each gene from each of his/her parents. To learn how meiosis contributes to genetic variation, students analyze the results of crossing over and independent assortment. Students also compare and contrast meiosis and mitosis, and they learn how a mistake in meiosis can result in Down syndrome or death of an embryo. This activity helps students meet the Next Generation Science Standards.

0.0 stars

Students learn about mutations to both DNA and chromosomes, and uncontrolled changes to the genetic code. They are introduced to small-scale mutations (substitutions, deletions and insertions) and large-scale mutations (deletion duplications, inversions, insertions, translocations and nondisjunctions). The effects of different mutations are studied as well as environmental factors that may increase the likelihood of mutations. A PowerPoint® presentation and pre/post-assessments are provided.

In a class discussion format, the teacher presents background information about basic human genetics. The number of chromosomes in both body cells and egg and sperm cells is covered, as well as the concept of dominant and recessive alleles. Students determine whether or not they possess the dominant allele for the tongue-rolling gene as an example.
