A researcher is trying to construct a molecular-based phylogeny of the entire animal kingdom. Assuming that none of the following genes is absolutely conserved, which of the following would be the best choice on which to base the phylogeny?
A) genes involved in chitin synthesis
B) collagen genes
C) β-catenin genes
D) genes involved in eye-lens synthesis

Option (B) is the correct answer of the following question.

Explanation:

Collagens are a family of enzymes that perpetuate and protect many of the body's tissues, with the exception of connective tissue, femur, fibula, pigmentation, and the caucasian eye (optic disc). It would be the best choice on which to base the phylogeny.

Other options are incorrect because they are not related to the given scenario.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!
