Example of plants mutations
- An individual with a mutation is called a mutant. when a mutation occurs in the reproductive tissues of an individual plants, it can be transmited to the next generation. when mutation occurs in somatic tissues, it will be limited only to that generation and affects only the cells in which it occurs.
- In the case of recombinantion, all the genes are already present in an individual and new variation simply results from the shuffling of those genes during gamats formation; there are no structural changes in genes.
- Genetic drift is the random fluctuations of gene frequencies as a result of sampling errors. Drift occurs in all populations, but its effects are most striking in small populations. Due to periodic reductions in population size, genetic drift can affect gene frequencies.
