Type of genetic cell division

Usage examples of meiotic.

Suppose a whole chromosome is, on average, likely to undergo one cross-over every time a sperm or egg is made by meiotic division, and this cross-over can happen anywhere along its length.

If the genetic unit we are considering is only 1 per cent of the length of the chromosome, we can assume that it has only a 1 per cent chance of being split in any one meiotic division.

It was created by the meiotic shuffling process, forged by the coming together of pieces of chromosome from your paternal grandmother and your paternal grandfather.

This is an average figure: by the luck of the meiotic draw, it is possible for particular pairs of brothers to share more or fewer genes than this.

New individuals are formed by the fusion of two isogametes, each produced by meiotic division.

Cases of it are known, for instance the intriguing phenomenon called meiotic drive.

How could it not, when it has such a huge unfair advantage in the meiotic lottery?

But the steps necessary to achieve exact diploid complements would be these: There must be intervention in gametogenesis in each parent just before meiotic division-reduction of chromosome number-that is, one would start with primary spermatocytes and primary oocytes, unreduced diploids.
