Variation is due to certain deviations from Mendel's laws but are these deviations enough to cause the large variation observed in the living world. Mutation is the current study to be made in this article.

Knowing the deviation or exceptions of Mendelian genetics are interesting but how do they affect evolution? how does variation influence evolution and how is variation maintained without getting absurd? Why do some phenotypes remain in extremely small proportions?

Mendel's laws of genetics are important for this level of studies. Here, you shall be introduces to the punnet square and dihybrid inheritance.

The study of genetics is involved with a lot of terminology. The discipline has its own language or vocabulary. Hence, before we sink deep into the study of genetics in subsequent parts of our lesson, we must get to know basic definitions in order to facilitate the understanding process

The very idea of how people look alike but different is actually amazing. A human always gives birth to a human but NO two humans are the same. Not even identical twins? How does genetics anwer this.
