#SPJ1
Early cleavage divisions in most embryos are also rapid. One reason for this is that cleaving cells have a modified cell cycle, in which the two gap phases, G1 and G2 are completely omitted, and the cells cycle rapidly between M and S phases. In addition, because the major cytoskeletal systems of the cells are largely devoted to mitosis (microtubules) and cytokinesis (microfilaments) during rapid cleavage division, there is typically an antagonism between periods of rapid cell division and cell movement. Thus as the embryo approaches gastrulation, there is a tremendous slowing in the rate of division (note the slope of the curve at the right).
Answer:
The correct answer is option B) "Species trees should be constructed using multiple loci (both nuclear and mtDNA)".
Explanation:
Gene genealogy is defined as the inference of relationships between individuals by using DNA testing in combination with the analysis of traditional genealogical and historical records. Gene genealogies could not be established using an unique genetic loci, since not always the same loci vary among individuals. Therefore, species trees should be constructed using multiple loci (both nuclear and mtDNA), to avoid erroneous inferences obtained by analyzing loci that do not vary among individuals.
