morphology, fossils, and molecular data

morphology, fossils, and molecular data, oday, almost all evolutionary relationships are inferred from molecular sequence data. This is because: DNA is the inherited material; We can now easily We use morphology, fossils, and molecular data to construct these. Why is this problematic?

what are xenobiotics

what are xenobiotics and where are they located at? A xenobiotic is a chemical substance found within an organism that is not naturally produced or expect to be present within the organism.

Trait determination

Trait determination.Discrete traits are determined by few loci, often only one. Quantitative traits are determined by many loci, sometimes hundreds. How do you think natural selection influences the evolution of these traits differently?
