It is true. In drosophila, distinct sets of maternal impact gene products must accumulate in the proper region of the embryo to ensure proper anteroposterior and dorsoventral development.
<h3>What makes Drosophila unique?</h3>
The use of Drosophila over vertebrate models has many technological advantages;
- they are simple and affordable to culture in lab settings,
- have a significantly shorter life cycle,
- produce huge numbers of externally deposited embryos
- may be genetically manipulated in a variety of ways.
<h3>Why is Drosophila referred to be the genetic Cinderella?</h3>
- Drosophila, which means "dew loving," is derived from the Greek word drósos.
- Fruit flies, or Drosophila melanogaster, are referred to as the genetic Cinderella.
- This term was given to them because of their 12-day lifetime, ease of culture, and ability to produce numerous offspring from a single reproduction.

The cell is in METAPHASE PHASE OF MEIOSIS. At this phase, the pairs of homologous chromosomes moves to the cell equator. These pairs of homologous chromosomes will be separated in anaphase I. The number of chromosomes remains constant until the first cell division is completed, then the chromosomes will be divided into two daughter cells.
Answer:
A.) Pollen are well preserved in the sediment layers because they are highly resistant to decay.
B.) Other indicators that can be used to determine past climates are through the analysis of the width of tree rings and the coral reefs formed underwater.
Answer:
a. disruption of mitotic spindle formation.
Explanation:
Vinblastine is a chemotherapeutic drug which is used to restrict cancer cell proliferation. During metaphase, it binds to microtubular proteins which play a very important role in mitotic spindle formation. If spindles will not form then during anaphase, the sister chromatids will not separate and mitosis will not take place. This is how hyper-proliferative cancerous cells are controlled from dividing and cancer is treated using this drug.
