<h2>Maternal effect</h2>
Explanation:
In maternal effect the phenotype of the progeny is decided by the genotype of the mother
- The female partner is one step ahead to her male partner
- The ovum transcribes some of its nuclear genes prior to fertilization and these genes are responsible for the development of embryo that is why these genes are called maternal effect genes
- This effect is observed in Drosophila
In the given question both male and female have brown eyes with Nn genotype,phenotype of the offspring will be decided by the genotype of mother(Nn) hence despite of having recessive genotype(nn) all the offsprings will show brown eyes
Answer:
As a negative guide, to demonstrate that perhaps the injection itself has no impact on the cell cycle.
A successful experiment has handled the same control group as the experimental group with the exception of the variable being examined, in this case the cytoplasm M-phase.
Answer: The cell that is being observed under the microscope have flagellum and lysosomes. The function of flagella is to help in the movement of the cell. This is considered as the locomotory organ of the cells. The membrane bound cell organelles lysosomes contains hydrolytic enzymes that is used by the cell for the breakdown of food ingested by cell.
Conclusion is that the cell can perform locomotion and digestion of small molecules.
Organelles can have different sizes from each other. As related to the cell, they are smaller than the cell they are contained in, and at different microscope amplifications, there can be seen different organelles, more and more as the amplification increases.
An investigative question related to this could be:
What is the cell-specific organelle size relation, and the organelle X-organelle Y size relation when in different microscope amplifications.
