Choose a genetics subject to study


Genetic Concepts

What is a gene? What are alleles? What are phenotypes and genotypes? What are heterozygosity and homozygosity? The answers are here.


Mendel's Laws

Gregor Mendel described laws of inheritance many years before the discovery of DNA. Learn about his laws and the genius behind them.


Non-Mendelian Inheritance

Epistasis, codominance, incomplete dominance, lethal genes, pleiotropy, multiple alleles and polygenic inheritance are all types of non-Mendelian inheritance.


Linkage and Crossing Over

What is linkage? Why is crossing over so important for biological diversity on Earth? Find out the answers here.


Sex Chromosomes and Sex-Linked Inheritance

The X and Y chromosomes are the sex chromosomes of the XY system. Learn about this as well as sex-linked diseases here.


Blood Types Review

What is your blood type? A, B, AB, O? Are you Rh+ or Rh-? Study the blood types, including the ABO, Rh and MN systems here.


Karyotypes and Genetic Diseases

44+XX or 44+XY: what is your karyotype? Study karyotypes and hereditary diseases with this review consisting of Q&As.


The Hardy-Weinberg Equilibrium

It is easy to understand the Hardy-Weinberg principle. In addition, learn about gene expressivity, gene penetrance and genetic drift.


Genetic Engineering

Here, you can find an easy explanation of recombinant DNA technology, cloning, the polymerase chain reaction, DNA fingerprinting and more.
