errors in DNA replication
Somatic mutations are not passed on to offspring because they occur in non-reproductive cells. These mutations only affect the individual in which they occur, and are not transmitted to future generations.
Mutations that occur at random are called spontaneous mutations.
Mutations in body cells are not typically passed on to offspring because they occur in somatic cells, which are not involved in reproduction. However, mutations in germ cells (sperm or egg) can be passed on to offspring.
cannot be passed on to offspring
Mutations that occur in body cells not involved in reproduction, such as skin cells or muscle cells, will not be passed on to the person's offspring because these mutations are not present in the egg or sperm cells that are passed on to the next generation. These mutations are considered somatic mutations and are not inherited.
Mutations occur at a relatively slow rate because cells have mechanisms in place to correct errors during DNA replication, reducing the chances of mutations. Additionally, mutations that have harmful effects on an organism's survival and reproduction are often removed from the gene pool through natural selection.
Interphase
Not all mutations are passed on to future offspring because mutations occur randomly and may not affect an individual's reproductive cells. Additionally, some mutations may be harmful to the organism, reducing its chances of survival and reproduction. Finally, mutations that do occur in reproductive cells may not be passed on if the individual does not reproduce or if the mutation is not present in the germ line cells.
Chromosome mutations occur most often during nuclear divisions because the process involves the replication and segregation of genetic material, which increases the chances of errors such as deletions, insertions, or rearrangements in the chromosomes. Additionally, factors like environmental exposure to mutagens or inherent genetic predispositions can further heighten the probability of mutations during cell division.
Mutations that occur at one single nitrogen base are referred to as a point mutation.
Such mutations are called point mutation or gene mutation.
Mutations happen in ALL living things (and also in viruses)!!!!!!
