genetic diversity

Question 1

how can genetic diversity be measured

Answer 1

by examining
dna base sequence
mrna base sequence
amino acid sequence in proteins

Question 2

which way of measuring genetic diversity is the best and why

Answer 2

examining dna base sequence-
comparing amino acid sequence isn’t reliable as dna base sequence is degenerate so the base sequence could be different
mrna has no introns so it doesn’t show the full genetic base sequence

Question 3

how are organisms grouped into a phylogenetic classification system

Answer 3

comparing their characteristics according to their evolutionary origins linking to a common ancestor into groups which don’t overlap
