Mendelian genetics is a fundamental aspect of genetics that explores how traits are inherited from one generation to the next. Named after Gregor Mendel, the father of genetics, this branch of biology is based on his pioneering work with pea plants. Mendelian genetics focuses on the principles of inheritance, including how dominant and recessive alleles determine an organism’s traits.

At the core of Mendelian genetics are Mendel’s laws of inheritance: the Law of Segregation and the Law of Independent Assortment. The Law of Segregation states that each individual has two alleles for each gene, which separate during gamete formation, with each gamete receiving only one allele. The Law of Independent Assortment explains how genes for different traits are passed independently of one another, leading to genetic variation.

Mendelian genetics also involves the study of phenotypes and genotypes, understanding how genetic variations manifest as observable traits and the underlying genetic makeup. Punnett squares are commonly used tools to predict the probability of certain traits appearing in offspring based on the genetic makeup of the parents.

This field has laid the groundwork for modern genetic research, influencing areas such as genetic disorders, evolutionary biology, and plant and animal breeding. Mendelian principles continue to be integral to understanding inheritance patterns and genetic variation.
