Answer:
One of the probable ways to determine how long ago any two species of bacteria diverged from each other is by drawing a phylogenetic tree.
Explanation:
- Phylogenetic tree are trees that show the ancestry of two species of interest and the relationship between them.
- The idea behind the construction of phylogenetic tree is darwins's "descent with modification theory".
- A phylogenetic tree is constructed using the similarities or differences in either physical characteristics, behavorial, or genetic buildup.
- Derived traits shared between the different species are the actual data used to construct a phylogenetic tree.

Hey there!
A warning safety sign is a sign that warns you that there may be a safety hazard around you.
Let me know if this helps :)
During gametogenesis, if
nondisjunction occurs in meiosis II (meaning that that at least one pair of
sister chromatids did not separate), the resultant effect will be two cells that
has the normal haploid number of chromosomes (n), one cell that has an extra
chromosome (n + 1), and one cell that has one missing chromosome (n - 1). In
summary, two of the gametes will be n, one will be n + 1, one will be n — 1.
