Tetraploidy will occur.

<h3><u>Explanation</u>:</h3>

The process of sexual reproduction is very necessary to maintain the genetic setup of the species over the races.

The normal chromosome content of a cell is called diploid state of cell. Its represented by the expression 2n. The cell division that takes place before the gamete formation is called meiosis. This cell division makes the chromosome number of the cells halved. So haploid cells are produced. Its represented by n.

Now as the gametes fuse, both the n becomes 2n and diploid state is regained.

But if the meiosis don't occur in the gametes, the gametes will remain 2n. So after fertilization, it becomes 4n. This state is called tetraploidy.

How does conduction differ from convection?
Free_Kalibri [48]

Answer:

Explanation:

I think the first one is correct.

The second one is half right (conduction works mostly in solids). The second part is not correct. Convection works mostly in gases.

The third one is wrong about waves. Conduction usually has direct contact of particles.

The last one is not correct. There is no visible movement of matter in conduction. The definition for convection is also incorrect.
