Answer:
Banyans are a fig. Australia has many native fig species, some of which grow in isolated pockets in arid areas of Australia. These include Ficus macrophylla, Ficus tinctoria, Ficus rubiginosa. I have seen Ficus brachypoda, Desert Fig growing on rock in Central Australia, but right next to small bodies of water such as permanent waterholes and deep wells. If they were able to colonise dune country and gibber desert they probably would have by now and they would be far better adapted than banyans.
I find it interesting that you have suggested banyans specifically when there is a host of other Australian native plants which thrive in arid country and create a self-sustaining ecosystem which supports food plants and a great diversity of animals.
Explanation:
Answer: False.
Genetic drift is a stochastic process that occurs randomly through time. It refers to random fluctuations in allele frequencies due to chance events (small population size).
Explanation: Factors that can affect genetic diversity are Genetic drift, mutation, selection, migration, non-random mating and recombination.
Of these factors, forces that majorly control the fate of genetic variation in populations are genetic drift and natural selection.
Genetic drift refers to random fluctuations in allele frequencies due to chance events (small population size).
Natural selection involves environmental conditions acting on wild plant or animal populations or species. Most fit in a selection refers to genotype or phenotype with greater average reproductive output over it's lifespan than other genotypes or phenotypes.
