Mr. Andersen uses chromosome beads to simulate both mitosis and meiosis. A brief discussion of gamete formation is also included.

Hank introduces us to nonvascular plants - liverworts, hornworts & mosses - which have bizarre features, kooky habits, and strange sex lives. Nonvascular plants inherited their reproductive cycle from algae, but have perfected it to the...

Hank gets into the dirty details about vascular plant reproduction: they use the basic alternation of generations developed by nonvascular plants 470 million years ago, but they've tricked it out so that it works a whole lot differently...

Paul Andersen explains how the process of meiosis produces variable gametes. He starts with a brief discussion of haploid and diploid cells. He compares and contrasts spermatogenesis and oogenesis. He explains how each person is...

Paul Andersen explains simple Mendelian genetics. He begins with a brief introduction of Gregor Mendel and his laws of segregation and independent assortment. He then presents a number of simple genetics problems along with their...

Howcast - Learn if autism can be inherited from pediatrician and child development expert Asma J. Sadiq, M.D. in this Howcast video.

In this video, we will delve into the core of genetics as we break down the fundamentals of chromosomes, explaining what they are and how they impact our traits. Discover the intricate structure of chromosomes, from the double helix of...

British medical researchers at Glenfield Hospital in Leicester have made significant progress in identifying a gene linked to the aging process. By studying the telomeres region at the ends of chromosomes, which protect them from damage,...

Evolution is the net change in organisms or a population over the span of many generations. This change in organisms or populations happens through DNA mutations and reconbination and is passed down to the next generation through...

A mutation is a random change in the DNA. Mutations can be neutral, which means it does not cause a change in a trait of the organism, or it could cause a beneficial or a harmful mutation. There are a few different types of mutations -...

Any chromosome that is not a sex chromosome.

Uncover the role of chromosomes in genetics, where these structures made of tightly coiled DNA house our genes. Learn how we inherit one set of 23 chromosomes from each parent, which explains why we might share traits with...

Dive into the fascinating structure of DNA, the molecule that forms the genetic blueprint for all living organisms. Understand how DNA's unique combinations determine traits and its ability to replicate ensures each cell in your body...

Meiosis is the process of cell division that gives us gametes such as sperm and egg cells. This video covers how the process works, why gametes are so important, and explains chromosomes.

In this video we recap chromosomes and then explain what DNA is, what genes and the genome are, and how we can use them to track the migrations of early humans.

In order to survive and grow, organisms require a constant supply of new cells. In this video we explore how these cells are generated through the cell cycle, with a particular focus on mitosis. We will also look at the role...
