The common housefly has a haploid number of 6 consisting of 3 long chromosomes (one metacentric, one acrocentric, and one telocentric); 3 short chromosomes (one metacentric, one acrocentric, and one telocentric). Draw and label a typical housefly primary spermatocyte in Metaphase I and spermatozoa at Telophase II.
Are all living organisms in nature unique in some way? Are for example every cherry blossom and every oak leaf a little bit different from every other flower and leaf on the planet? I know that some animals (like earthworms and aphids) and some plants reproduce by naturally cloning themselves and thus have identical DNA. But is it still always possible to find something that is different between them (despite their identical DNA)?
Can two cherry blossoms ever look EXACTLY the same or not (the difference might be so small that it can not be seen by human eyes and maybe not even with an advanced microscope, but is there still always a tiny difference if you go to the level of cells or elementary particles)?
I would highly appreciate it if you could help me answer this question!
If the quantity of DNA in a cell at G1 of the cell cycle is 5 picograms. What will the quantity of DNA in that cell be at G2 phase of the cell cycle? Give a reason

An XXX individual may be result of an abnormal complement of chromosomes in the egg or sperm. At what point of meiosis does this abnormality arise in female and males? What is it due to? Make use of diagrams to explain your answer
a. A primary spermatocyte has the genotype AaBbee. The A and B loci are linked in cis configuration on the long arm of an acrocentric chromosome. The E locus is on a metacentric chromosome. Show the chromosomes containing these genes at metaphase I telophase I and telophase ii using diagrams. Diagrams must clearly labelled
B. Using information in a) show the resulting telophase I and telophase ii diagrams after a crossover between the A and B locus has occured at Pachytene of meiosis. Diagrams must be clearly labelled
An important function of meiosis is to reduce the chromosome number to exactly half. How is this done? What makes such a process necessary
A primary spermatocyte has the genotype DdEe. These genes assort independently at meiosi
I. Show the chromosome containing these genes Metaphase I telophase I and telophase ii usingdiagrams. Diagrams must be clearly labelled and show metacentric chromosomes undergoing meiosis
