Answer:
crossing over
Explanation:
This occurs between prophase 1 and metaphase 1.
The cell wall is a tough and rigid layer that surrounds some types of cells. It is located outside the cell membrane and its main function is to provide rigidity, strength, protection against mechanical stress and infection. It can also provide the cell with limited plasticity that will prevent the cell from rupturing due to turgor pressure.
Populations at genetic equilibrium often occur in nature
Answer:
Meiosis is important for organisms that reproduce sexually because it is the cell division that serves to obtain gametes or sex cells.
Explanation:
Meiosis is a reductive cell division, involved in the gametogenesis process, where from a diploid cell haploid cells called gametes are obtained.
The gametes, also called sex cells, are responsible for containing the genetic information that each individual will transfer to their offspring.
In sexual reproduction, the importance of gametes is that the paternal and maternal gametes unite in a process called fertilization, to give rise to a diploid cell called a zygote.
