Mitosis, Meiosis, and Sexual Reproduction
Learning Outcomes Understand how mitosis, meiosis, and random fertilization all result in genetically unique individuals As you now know, genetic variation is very important. Genetic variation is introduced in multiple ways, including changes in mitosis, crossing over and random orientation in meiosis, and random fertilization. The video below offers you a nice overview of how Read more »
Mitosis
Learning Outcomes Identify the characteristics and stages of mitosis The mitotic phase (also known as M phase) is a multistep process during which the duplicated chromosomes are aligned, separated, and move into two new, identical daughter cells. The first portion of the mitotic phase is called karyokinesis, or nuclear division. The second portion of the mitotic Read more »

Cloning
Learning Outcomes Recognize technologies used for molecular, cellular, and reproductive cloning Molecular Cloning In general, the word “cloning” means the creation of a perfect replica; however, in biology, the re-creation of a whole organism is referred to as “reproductive cloning.” Long before attempts were made to clone an entire organism, researchers learned how to reproduce Read more »
Chromosomal Structural Rearrangements
Learning Outcomes Understand the impact of translocation between non-homologous chromosomes during meiosis or mitosis Cytologists have characterized numerous structural rearrangements in chromosomes, but chromosome inversions and translocations are the most common. Both are identified during meiosis by the adaptive pairing of rearranged chromosomes with their former homologs to maintain appropriate gene alignment. If the genes Read more »
Sexual Reproduction
Learning Outcomes Understand how sexual reproduction leads to different sexual life cycles Sexual reproduction was an early evolutionary innovation after the appearance of eukaryotic cells. It appears to have been very successful because most eukaryotes are able to reproduce sexually, and in many animals, it is the only mode of reproduction. And yet, scientists recognize Read more »
Putting It Together: Cell Division
Mitosis and meiosis are both forms of division of the nucleus in eukaryotic cells. They share some similarities, but also exhibit distinct differences that lead to very different outcomes (Figure 1 and Table 1). Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new cells. The nuclei Read more »
Introduction to Errors in Chromosome Number
Examine karyotypes and identify the effects of significant changes in chromosome number We previously learned how errors in mitosis can potentially lead to cancer. What could errors in meiosis result in? In this outcome, we’ll learn what happens when errors occur in chromosome number. What You’ll Learn to Do Identify a karyotype and describe its Read more »
