Extranuclear inheritance occurs becausea. certain genes are found on the X chromosome.b. chromosomes in the nucleus may be transferred to thecytoplasm.c. some organelles contain DNA.d. the nuclear membrane breaks apart during cell division.e. both a and c.
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:
Extranuclear inheritance occurs because
a. certain genes are found on the X chromosome.
b. chromosomes in the nucleus may be transferred to the
cytoplasm.
c. some organelles contain DNA.
d. the nuclear membrane breaks apart during cell division.
e. both a and c.
