cells in the vegetal half of the embryo should be unpigmented those in the animal half and there should be heavily pigmented.
Explanation:
The Yolk molecules moving in the vegetal halves of the egg which is the case in most of the animals, slows down the cell division. These lesser division area or the zone demarcates the area to be vegetal pole and due to lesser cell division, it becomes unpigmented or less pigmented Based on the observation time and perspect with assuming no movement.
The pole opposite to the vegetal, is animal pole which with absence or less of yolk, gets more ability to divide and hence become more pigmented or heavily pigmented. This brings polarity to the egg and becomes telolecithal egg.
Answer:
Genetic drift
Explanation:
Based on the information given here, the observed genetic variation is most likely an example of Genetic drift .
Genetic drift is the variation in the relative frequency of different genotypes in a small population, owing to the change disappearance of particular group of genes as individuals die out do not reproduce.
The above mentioned information indicate a typical example of Genetic drift
<span>If vinblastine prevents assembly of the spindle, then it interrupts cell division in Profase 1, when the assembly of the spindle begins. Paclitaxel prevents the depolymeritation of the spindle, so it will interrupt cell cycle in Anaphasis, when the dissasembly of spindle takes place.</span>
