Coral reefs are formed from coral polyps. When the polyps release calcium, a free swimming coral larvae is formed and which attack themselves to attached rocks.
The relative time of divergence from a common ancestor can be estimated by comparing the nucleotide/protein sequence.
<h3>What is sequence homo-logy?</h3>
In molecular biology, sequence homo-logy means the degree of similarity between sequences due to a common ancestor.
A sequence is a given fragment of a single DNA strand where nucleotides are arranged in a specific linear order.
Divergence or separation between lineages is directly proportional to the level of sequence homo-logy.
In conclusion, the relative time of divergence from a common ancestor can be estimated by comparing the nucleotide/protein sequence.

Alphonse Bertillon was a French criminologist who first developed this anthropometric system of physical measurements of body parts.
Answer:
2 organisms can have the same physical traits but no matter what, every single living creature has different DNA. Like how twins can look the same but their DNA won't be exact.
Explanation:
