Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
why The chromatids formed by
recombination within the inversion loop of a pericentric inversion
heterozygote are genetically unbalanced?
When the region between two breaks of the same chromosome rotate 180°, it results in chromosomal aberration called inversion. When the inversion occurs between the arms of the same chromosome, it is called paracentric but when inversion involves the centromere along with arms it is called pericentric. Heterozygotes for the inversion are generally phenotypic normal but their gamete’s quality and fertility can be affected causing the recombination in inverted region.
