Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during mitosis or meiosis. There are three forms of nondisjunction:
1. failure of a pair of homologous chromosomes to separate in meiosis I ,
2. failure of sister chromatids to separate during meiosis II, and
3. failure of sister chromatids to separate during mitosis.
As a consequence of nondisjunction abnormal chromosome numbers appears. If nondisjunction occurs during the meiosis I (anaphase I), this means that at least one pair of homologous chromosomes did not separate. The consequence is two cells that have an extra copy of one chromosome and two cells that lack that chromosome.
It is inportant because kelp forest provide food and shelter for most sea creatures and provide foo for humans as well. It helps you undertsand that in the Maringe life there are plants that grow in saltwater like seawed and that they porvide food and also protection for smaller sea creatures.HOPE THIS HELPS.LET ME KNOW IF IT DOES.

Answer:
The evolution of a species is driven by many evolutionary mechanisms two of which are: natural selection and the genetic drift.
The natural selection selects the species or the alleles which increase the reproductive success of the species in a given environment whereas the genetic drift cause evolution by randomly selecting the alleles based on the sampling error. The genetic drift selects the alleles or species by chance and not on the beneficial and harmful basis.
In the given question, If natural selection favours the one trait of the species on the basis if it provides fitness then it could result in a genetic drift of alleles of another trait as it is purely based on the chance.
Epiphytes show commensalism.
