Mutations that span more than one gene are called chromosomal mutations because they affect the structure, function, and inheritance of whole DNA molecules (microscopically visible in a coiled state as chromosomes). Often these chromosome mutations result from one or more coincident breaks in the DNA...
Genes are a hereditary unit in organisms i.e., it helps in the inheritance of traits from one generation (parents) to another (offspring). Hence, the nucleus controls the characters and functions of cells in our body. The primary function of the nucleus is to monitor cellular activities ...
An inevitable consequence of variation,inheritance, and differential reproduction is that, over time, the frequency of traits that render individuals better able to survive and reproduce in their presentenvironmentincreases. As a result, descendant generations in a population resemble most closely the mem...

In this type of heredity non-nuclear DNA is passed to offspring. Types of cytoplasmic inheritance include vegetative segregation, uniparental inheritance, and biparental inheritance. What are the characteristics of mitochondrial inheritance? Mitochondrial inheritance refers specifically to the inheritance of ...
