A clear video to review the basics of genetics – Heredity- and its vocabulary with a dihybrid cross as a Punnett square to clarify it all. (2´07´´)

A very short video to tell us the Mutation concept and its environmental causes.

but I prefer this other one with more or less the same content in it:


In case what you need is a great bold teacher to explain you carefully some aspects of genetics, then here you have some extra sessions by the awesome Professor George Wolfe, videos from Thinkwell’s online Biology.

They have been selected according to your 4º ESO level, even if some of these contents were not explained in our lessons.

The Human Genome Project: Applications 15´24 ´´ (it must be one of his very first records).

With a similar basic philosophy as Porfessor George Wolfe´s videos, I have found this young biology teacher with his own youtube channel (bozemanbiology) where we can find his homemade online lectures. According to our syllabus and related to this unit I suggest you could find useful these two links:

Here you have a wonderful compilation of video lectures by Professor George Wolfe, to teach us the different topics about Human as an Organism. In this compilation I have chosen the videos related to our 3ESO Biology Syllabus, some of them have extra information that you will learn next years. This compilations is also very suitable as an IGCSE revision.

Thanks to the world wide web we have a wonderful teacher ready to explain us the different systems in several video-sessions  whenever we want (all of them about 10 minutes) so we can replay, stop, pause, or rewind  this marvelous teacher. Enjoy it,  I hope you like his lessons as much as I do.
