Mutations can be harmful, beneficial, or have no effect on an organism.
Types of Genetic Mutations
There are several types of genetic mutations, including point mutations, insertions, and deletions. Point mutations involve a change in a single nucleotide base pair, while insertions and deletions involve the addition or removal of nucleotides. These mutations can lead to changes in the amino acid sequence of a protein, which can affect its structure and function.
Inheritance and Genotype
Genetic variations are inherited from parents and can contribute to an individual’s unique characteristics. The inheritance of genetic traits follows specific patterns, such as Mendelian inheritance, which involves the transmission of traits from parent to offspring according to certain rules. However, not all genetic variations are inherited in a simple manner, and complex traits can be influenced by multiple genes and environmental factors.
Genotype refers to the set of genes an individual possesses for a particular trait or set of traits.
