The probability is 1/16 that a gamete will receive only paternal chromosomes. In life
cycles that alternate between haploid and diploid stages, fertilization doubles
the number of chromosomes per cell, The pairing of chromosomes along
their lengths , which is essential for crossing over is referred to as synapsis
Answer:
The centromeres split and the sister chromatids are pulled to opposite poles of the cell. The chromosomes reach the poles and stop moving.

Explanation:
The cellular communication is an important aspect of unicellular and multicellular organisms in the environment. The cellular communication may differ in the bacteria, plants and animals but the mechanism of cellular communication remains the same.
The mechanism involves the receptors, change in the structure of receptors which triggers the signal to respond and then the response of the cell. Therefore the evolutionary biologists must look at this mechanism and the molecules associated with this mechanism.
The biologist can look at these receptors and the ligands which initiate the transduction process in the organisms.
