Answer: Hi (warning change the wording or you may get charged for plagiarism!)
The idea of the atom is dated back way back to Aristotle's day as you know. But you may not have known that there were many ideas about what the atom would be. some believed that there was only 1 fundamental particle, others however believed that there was no atom at all and that you could just keep cutting the cake forever and never stop. Aristotle's four elements (fire earth air and water) where believed to be fundamental units that everything was made of. Different things such as would and glass would be a combination of earth fire and air perhaps. You may see now how different this idea is from the atom nowadays. there are magnitudes of different types of atoms. the 118 elements you know of are only a fraction of the thousands of isotopes (an isotope is an atom with slightly more or less nuetrons than the normal one with as many nuatrons as protons).
The answer is; B
This genotype is similar to that of one parent. It assumes that nondisjunction of chromosome did not happen and there was no fusion of gametes. The offspring cannot have exact genotype as one parent in sexual reproduction, In sexual reproduction, the offspring gets half of its chromosomes from each parent. This is why the chromosome number is reduced by half in the formation of gametes through the process of meiosis.
The optimum range seems most applicable,
