Answer: d. None of the above
Sustainable development involves the maintenance of human community with the adequate and judicious use of natural resources so that these resources will be available for future use. Small societies can maintain stability in the long terms by following notion of sustainable development. Smaller societies have a smaller demand for resources. As, lesser the number of individuals lesser will be the demand for resources and these resources will be available for future hence, smaller societies will maintain stability. Smaller societies can be governed by internal controls more effectively than larger societies because members can control the use of resources by creating awareness among themselves and use of resources can be checked upon. Small societies rely more heavily on legislation and military forces because these can ensure that all norms of resource conservation and sustainable development are strictly followed by members of the society.
Therefore, all options are useful for maintaining stability in the society.
So, recessive allele 'd' are dwarfs.
The dominant allele is 'D' determines tall.
All you have to do is try to cross the alleles together to get either a homozygous or heterozygous remain. So, you should be able to get Dd or DD.
Meiosis is the cell division in which there is a formation of chiasmata......which lead to variation......
