To determine the number of chromosomes present in the meiocytes of a housefly, we can follow these steps: Step 1: Understand the relationship between gametes and meiocytes.- Gametes are the reproductive cells (sperm and eggs) that are haploid, meaning they contain half the number of chromosomes...

Mckee, B., Hafera, L., Vrana, J.A. 1992. Evidence that intergenic spacer repeats ofDrosophila melanogasterrRNA genes function as X-Y pairing sites in male meiosis, and a general model for achiasmate pairing. Genetics 132: 529–544. ...
ZO-ZZ systemis prevalent in moths, like the Marsh Marigold. Male moths have ZZ sex chromosomes and produce a single type of gamete, the Z. In contrast, females have ZO allosomes (sex chromosomes). Hence, during gamete formation, Z behaves as a univalent, as it has nothing to pair ...
No comparable studies exist on the formation of the female gamete because of the higher difficulty for visu- alisation of oogenesis. However, a reduction in fertility has frequently been reported for B chromosomes in many animal species. As pointed out by Camacho [2005], 'fer- tility is one...
