Question 11 If a trait has low heritability, genetically identical siblings are expected to: O Show dissimilar phenotypes when raised in dissimilar environments Have dissimilar genotypes when raised in dissimilar environments Show identical phenotypes when raised in different environments O Have a greater chance of mating with one another than with a non-relative Question 12 3 pts True/False Organismal complexity (how complex an organism is) is not correlated with genome length but is correlated with the number of protein coding genes O True 3 pts False
3 pts Question 9 HOX genes are highly conserved among animals. This Gives a mechanism to Von Baer's observation of the similarity among early embryo forms of distantantly- related lineages O Indicates they have accumulated many non-synonymous changes over time O Suggests the genes have different functions in different lineages Means they can be used to determine the relatedness among recently diverged lineages Question 10 3 pts A group of scientists in 2012 carried out a study in which they took multiple skull measurements from dinosaur fossils and modern bird skulls. They determined that modern adult bird skulls resemble the embryo skulls of ancestral dinosaurs. With respect to skull morphology, birds represent what kind of heterochrony as compared to dinosaurs? Recapitulation O Polymorphism O Stabilizing selection Paedomorphism
