History is the answer. Art, music and clothing are all trends where history is not
Answer
Crossing over is the phenomenon in which exchange of chromtids occur between non sister chromatids and result into recombinant chromatids, which is an important tool for evolution and bring about genetic changes in offsprings as compare to their parents.
No crossing over
If no crossing over occurs, it means no exchange of chromatids between non sister chromatids of homologous chromosomes, then no recombinant chromatids will be formed.
Result
At the end of meiosis II, when four haploid cells are formed, all these cell will contain similar chromosomes as present in parent. Thus chromosomes are non recombinant because of no crossing over.
Answer:
Yes, It is theoretically possible seeing that one or both of them have the gene for white eyes.
Explanation:
1) We must ration out the oils because we will be running out before 50 years & we must have new technology to replace the Fossil Fuels.
2) If we allow the World's resources to be used as fast as they are then at some point we will run right out of that resource forever.
3) There should be someone to take responsibility for the mining and usage of the World's resources before its too late and it should not be too long before we reach the point.
