Mutation Lethal

The mutation is lethal

A lethal mutation is a mutation that leads to the death of the mutant organism even before it leaves offspring. This means that the mutant cannot pass on its genes to the next generation.

One of the reasons for the appearance of lethal mutations is the mutagenic effect on the body. Mutagens can be either external (for example, radiation, chemicals) or internal (for example, errors in the genetic code).

Another reason for the appearance of lethal mutations may be that the mutant's body lacks some important component necessary for survival. For example, if a mutant cannot produce a particular protein that is essential for its function, it will be at risk of dying.

Lethal mutations can have various consequences for organisms. Some mutants can be completely destroyed before they leave offspring, leading to the extinction of their species. However, other mutants can survive and pass on their genes to subsequent generations, which can lead to the emergence of new species of organisms.
In general, lethal mutations are an important element of evolution, since they can lead to changes in the gene pool of species and the emergence of new forms of life.

Conception Crossing

Lethal mutation (lat. mutatio “change”, “mutation”) - the transformation of an inherited trait into a changed one (most often - harmful changes in the properties and functions of the body). Description of M. l. (negative effect) - a mutation that leads the organism to incapacity and death before it produces the next generation (death right now). Such mutations are characteristic of bacteria - with M. l. bacteria die from exposure to the antibiotic. In cases where a cell mutates immediately, and not after several generations, this is called M. M. D. in plants M. l. dangerous. When the overwhelming number of plants in the previous generation is destroyed, MD occurs.
