Answer:
A DNA barcode is a short, standard gene segment of an organism that has been identified in a gene bank, used to identify unknown species by comparison with the DNA sequence of the gene bank. .
Think about the actual physical process happening in the cell - the allele (or versions of a gene) are literally physical pieces of DNA strung together into chromosomes. And as the cell divides to form gametes, those chromosomes randomly assort themselves into the two new cells (conditional that each new cell gets one copy of each chromosome, in the case of gametes)...<span>

Answer:
Phylogenetic trees reconstructed from molecular sequences are often considered more reliable than those reconstructed from morphological characters, in part because convergent evolution, which confounds phylogenetic reconstruction, is believed to be rarer for molecular sequences than for morphologies
Explanation:
The object to life is to reproduce. after that nature really doesnt care what happens to you. so if you can reproduce hundreds of thousands of times over a month. Without much effort either. would you.
