Concept explainers

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:

Question

The two main sources of genetic variation from meiosis are ________.

random orientation of homologous pairs and mutation

crossing over and random mutation

random orientation of homologous pairs and crossing over

Definition Definition Genetic variation refers to the differences in DNA sequence among individuals of the same species. These variations can occur due to mutations, genetic recombination, and natural selection. Genetic variation plays an important role in evolution, as it allows for the selection of traits that enhance the survival and reproduction of organisms in changing environments.
