Inheritance is a fundamental concept in genetics that explains how traits and characteristics are passed from parents to offspring. This process is governed by the transmission of genetic information encoded in DNA, which is organized into genes. These genes are inherited in specific patterns and determine various physical and biological traits.

The study of inheritance primarily involves understanding Mendelian genetics, which is based on the principles first described by Gregor Mendel. According to Mendelian principles, traits are inherited according to dominant and recessive alleles. Dominant alleles mask the effect of recessive alleles, and the combination of these alleles in an organism’s genotype determines its phenotype.

Inheritance patterns can be categorized into several types, including autosomal dominant, autosomal recessive, and X-linked inheritance. Autosomal dominant traits require only one copy of the dominant allele to be expressed, while autosomal recessive traits require two copies of the recessive allele. X-linked inheritance involves genes located on the X chromosome and can affect traits differently in males and females.

Recent advances in genetics have expanded our understanding of inheritance beyond Mendelian patterns, incorporating concepts such as incomplete dominance, codominance, and polygenic traits. These modern insights help explain the complexity of genetic inheritance and its impact on health, development, and evolution.
