Today, the common type of banana we eat is a Cavendish banana. They arose from chance mutants that were produced sexually from wild banana plants. The Cavendish banana is infertile and can only be produced by cloning root shoots. Large commercial growers worldwide now plant only the mutant type. Some information about both types of banana is recorded in the table.
Growers on large banana plantations that supply food commercially have chosen to limit their plantings exclusively to Cavendish banana plants. Why are scientists warning that exclusively growing this mutant type by asexual reproduction presents a serious disadvantage
1.The loss of an adequate Cavendish banana seed supply could result in extinction of both varieties of plants.
2. The changes in characteristics from a parent plant to a clone will produce inconsistent plants that are less healthy.
3.The lack of genetic variability among clones puts the whole species at increased risk of extinction through a catastrophic disease or pest.
4.The increasing number of homologous sets of chromosomes crossing over with each successive generation of clones will eventually result in widespread death of banana plants.
