Due to a demand for land in an urban area, a forest has been burned. howwill this affect the carbon cycle?

Much more carbon will be present in the landscape, seeing as plants which absorb it have been removed in quite large quantities. A major avenue of carbon absorption has thus been removed. In addition, immense amounts of carbon will have been released into the air from the burning itself. This carbon, combined with the otherwise existing carbon that is now stuck in the atmosphere (with no trees to absorb it), will contribute to pollution.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

what are the options
