Germinal variation is the type of variation that occurs only in germplasm of organisms.so,only the variations from the germplasm and the gametes are passed on the offsprings.It may be apparent from the birth of the individual or may develop at any stage of life of the organism.

What is the significance of the increase of nucleoli in the nucleus of oocytes?

An increase in nucleoli in oocytes is indicative of increased metabolic and synthetic activity in preparation for fertilization and embryonic development. Nucleoli produce ribosomal RNA and are involved in protein synthesis, which is crucial for supporting the rapid cell division and growth that occurs during early embryonic development.


Germinal matrix hemorrhage?

A Germinal matrix hemorrhage is a bleeding into the subependymal germinal matrix with or without subsequent rupture into the lateral ventricle. The microcirculation in this particular area is extremely sensitive to hypoxia and changes in perfusion pressure. It is most frequent before 35 weeks gestation and is typically seen in low birth-weight babies.


Why sexual reproduction also called germinal reproduction?

because sexual reproduction involves the germ cells


Which cell type is found in greatest abundance in the germinal centers?

B cells are the cell type found in greatest abundance in germinal centers. These B cells undergo proliferation, somatic hypermutation, and selection to produce high-affinity antibodies.


What happens during germinal stage and how long does it last?

The germinal stage is the first stage of prenatal development that begins at fertilization and lasts for about two weeks. During this stage, the zygote undergoes rapid cell division and travels down the fallopian tube to the uterus, where it implants in the uterine lining. The germinal stage ends with the formation of the blastocyst, which is the early stage of embryonic development.
