Do you sneeze when you go from dark to light areas? Twenty-five percent of the population does! It turns out that the characteristic is due to genetic code. Explore why this happens with a video from the Veritasium playlist that...

Two meters worth of DNA fits into a cell that is only two micrometers wide thanks to chromosomes. A video, part of a Fuse School Biology playlist, explains what chromosomes are and how they work. It describes where they are found and how...

Scholars often find new vocabulary overwhelming—help break it down for them. A helpful video addresses the vocabulary associated with genetics and cell division. It offers the definition of each and a short explanation. Cartoon graphics...

A human egg cell measures more than 30 times the size of a human sperm cell. An engaging video in the Fuse School playlist discusses the differences between sperm and egg cells. It highlights the reasons for the differences as they come...

Doctors sometimes order a karyotype, a picture of the chromosomes present in a single cell, in order to check for chromosomal abnormalities or rare diseases. The video explains the relationship among genes, chromosomes, and karyotypes....

The video Introduce class members to the cell cycle and chromosomes with a video that explains the difference between diploid and haploid chromosomes.

Bye bye, Y! Is the most fundamental difference between men and women slowly going away? Science scholars discover the story behind the ever-shrinking Y chromosome in an interesting human biology video. Topics covered include...

The ancient Romans use the saying "When a mule foals" as a metaphor for the impossible. Viewers learn through a video lesson the genetics behind hybrid breeding, giving more meaning to this saying. The instructor explains the...

Women just have that X factor! High schoolers watch a short video about X chromosome inactivation, which explains how identical twins can differ genetically even though their DNA sequence is the same.

What makes men so manly? Video begins with a discussion of the y-chromosome and tracks it back through history. It surprises many to learn everyone seems to have one common male ancestor. Then it discusses sexual dimorphism and the...

Gynandromorphy is when an animal is part male and part female. Video explains the development of gynandromorphs from zygotes. It describes the various combinations of chromosomes that produce different classifications of dual-sex...

Potatoes have more chromosomes than humans. A video explores the number of chromosomes various species have and the theories of the differences. It discusses the process of how genes combine as well as the processes of making extra copies.

As we get older, we age, our bodies and minds deteriorate, but this isn't true of all species. The video begins with why we age and what biological processes cause aging. Then it covers research on worms, mice, and other animals that...

Why do some people look young at age 60 while others look old at age 30? Elizabeth Blackburn discovered it is all related to telomeres and telomerase. Her discoveries have not only led to a better understanding of aging, but also to a...

An informative video begins by showing scholars how chromosomes are like encyclopedias. The instructor then explains and differentiates genome, chromosome, sister chromatids, nucleosomes, DNA, genes, and base pairs. 

Ever wonder why most calico cats are female? An engaging video explores the inactivation of one of the x-chromosomes in female cats, allowing for calico coloration. 

Scholars analyze Morgan's fruit fly lab to learn how genes are linked. The instructor shows that the data from a dihybrid cross was not what Morgan expected, and when re-crossed numerous times, the data did not change. Viewers see gene...

Scholars see, through a monohybrid cross, how alleles are distributed during meiosis. The video instructor then explores Thomas Hunt Morgan's research on fruit flies, determining that genes are located on chromosomes and showing that...

Although we cannot clone ourselves yet, our bodies make copies of our cells every day. The video begins by defining diploid and haploid. Learners see the cell cycle and begin to understand what happens in interphase before mitosis...

Are the only mutants you know Ninja Turtles or X-Men? The video explains both gene mutation and chromosome mutation. It includes the subtypes of mutations for each major type, the times when mutations are more likely to happen, and...

Until the 1960s, the life expectancy of a hemophiliac was only 11 years. An informative video explains how to solve a Punnett square when there is a sex-linked trait — in this case hemophilia. It includes a discussion of the xy...

Your DNA is restless; have you taken your chromosome walking today? A video helps clarify how to count chromosomes during each stage of division for both mitosis and meiosis. It includes a comparison of division and reductive...

What did one cell say to his sister when she stepped on his toe? Mitosis! The video details the process of using division to multiply that is better known as mitosis. It includes the four steps of mitosis: prophase, metaphase, anaphase,...
