A.Prosauropods and sauropods are two groups that are closest relatives of birds and other theropods.
B.Monophyletic (Monophyletic groups and lineages are the fundamental basis of taxonomy and evolution as a whole really. Everything within a monophyletic group is the descendent of a single common ancestor and thus are the clades we typically talk about in biology and palaeontology.)
C.1.Crocks and relatives
2.Pterosaurs
For the four evolutionary processes below, indicate: how they affect allele and genotype frequencies within a...

Part A: Which two groups are the closest relatives of birds and other theropods? Part B: If you formed a group of "flying things" that included pterosaurs and birds, would that be a...
For the four evolutionary processes below, indicate: how they affect allele and genotype frequencies within a population, whether or not these effects are random, and how they affect differentiation between populations. Number your answers as indicated in the table below to indicate which part of this question you are answering: Process Within-population allele & genotype frequencies Random?Y/N Genetic differences between populations #1 #9 Natural Selection Genetic Drift Mutation #6 #10 . #11 Migration between populations #4 #12
2. Which of the following correctly describes how inbreeding will affect genotype and allele frequencies in Hardy-Weinberg populations? Genotype and allele frequencies will be unaffected. The frequency of heterozygotes will decrease, but allele frequencies will be unaffected. The frequency of homozygotes will increase, and deleterious alleles will decrease. Beneficial alleles will increase in frequency, as well as the genotypes containing those alleles. Genotype frequencies will return to H-W expectations after 1 generation of random mating. 3. Consider a population with...
