What structure is most important in forming the tetrads?
Vladimir79 [104]

Answer:

The correct answer will be option- synaptonemal complex.

Explanation:

The tetrad arrangement of the genetic material in an organism is mediated by a highly conserved structure known as the synaptonemal complex.  The synaptonemal complex is formed during the prophase I of the meiosis I which attaches the chromatin of the homologous chromosomes.

The synaptonemal complex is a proteinaceous structure which is formed by the two lateral ladders like elements with a central portion composed of the central element. The chromatin gets attached to the lateral elements while the central a portion bridge space between the two ladders thus help in the formation of the tetrad.

Thus, option- synaptonemal complex is the correct answer.

Explanation:

The smell is adaptation for pollination.This is because it attracts insects which carry on the process of pollination.

Its possible Endothermy characteristic  is for mimicry Its releases  heat to attract  the pollinators- blowflies.The endothermic mechanism  is well pronounced during flora development: which further buttress the fact that this  is related to pollination to attract blowflies, and not to thermoregulation.
