In these 36 lessons, we'll focus our attention on Mendelian genetics and genetic mutation. We'll start with lessons that cover Gregor Mendel, his work and his findings (phenotypic rations and theories of alternate alleles, dominance, degregation and recombination, Laws of Mendelian Inheritance, etc). Next, we'll look at the concepts and underpinnings of segregation and independent assortment.

Following this, we'll cover pertinent laws of probability that come into play when examining genetic interactions and problems. From there, we'll move on to cover genetic dominance, intermediate inheritance, codominance and cases of multiple alleles. Then, we'll look at epistasis (the interaction between genes) and patterns of inheritance (including polygenic inheritance and Pleiotropy, which occurs when a single gene influences multiple phenotypic traits).

We'll also learn about linked genes and genetic mapping, which will teach us about crossing over and recombination, recombination frequencies, and Morgan's work linking genes to chromosomes. Additionall, we'll explore sex-linkage and pedigree charts by looking at several specific sex-linked traits in humans and using pedigree charts to solve problems and determine possible genotypes.

Our next three lessons will look at problems in heredity, including chromosomal aberrations and translocations like 14/21 Downs. Last, we'll wrap up with a look at genetic mutation. As part of this, we'll examine several different forms of point mutations, and we'll learn about genetic mutation via both insertion and deletion. We'll also be introduced to the notion of genetic screening, why it is used, what it looks for, and how it works.

too easy

Not enough information. Far too simple. Need long, hard inheritance and probability.

Excellent

I found this topic very confusing until I watched this video.

Poor explanation

~ Hannah6

Not worth purchasing, did not explain how you get trisomy 21 at all as chromosome 21 is still translocated on chromosome 14 in his diagram. Very confusing and unclear.

Ahaaa!

Now its making sense!

Hah, i thought this was gonna be about somethin else >.<

Male and female

At 6:50 male is XY and female is XX, the diagram doesn't match the explanation.

Gene Mapping & recombination

This video would have been more helpful if you would have went through an actual pedigree that showed how to identify recombination in different generations.
