Among the most frequently used species identification methods are: The evolutionary relationships between the unknown sequence and a set of known standard sequences are estimated using phylogenetic trees.
<h3>What is a phylogenetic tree?</h3>
Among the most commonly used species identification methods are: The evolutionary relationships between the unknown sequence and a set of known reference sequences are estimated using phylogenetic trees.
A phylogenetic tree is a diagram that depicts the evolutionary relationships between organisms or groups of organisms.
Scientists consider phylogenetic trees to be evolutionary hypotheses because the proposed relationships cannot be confirmed in the past.
Thus, every individual of same species are related to each other, so scientists can analyze another specimen from the same species.

The answer is light.
One of the factors that affect photosynthesis is light. Without light, the photosynthetic rate is reduced or even stopped which consequently affect algal growth. With increasing depth in the ocean, there is less sunlight present. Still, a<span>lgae have accessory photosynthetic plastids other than the chloroplasts</span><span> that can absorb different light in greater ocean depths. This helps them to maximum use sunlight in such conditions. But, in the end, at some particular depth, they would not be able to survive.</span>
<span>There are four possible phenotypes with a dihybrid testcross. The 1:1:1:1 ratio means that there is an equal chance of any of the four expected phenotypes in the offspring.</span>
This change in chromosome number is the result of B. Fertilization. Both of the individual gametes from the male and female combine together to produce a zygote or developing offspring that is diploid in most cases, and possess both sets of genetic content or chromosomal information, one from each parent.
Usually the lava flows come towards the end of the eruption, once the magma has lost enough of its volatiles to flow more quietly. Cinder cone eruptions are comparatively short lived, and thus cinder cones are much smaller features than stratovolcanoes and shield volcanoes (usually no more than a mile at the base).
