QUESTION 2 Axolotls are unusual looking amphibians that reach adulthood without undergoing metamorphosis. There is a gene (white) in axolotls that controls how much pigment is being produced. The dominant D allele leads to dark gray coloration and the recessive d allele leads to white colored axolotls. A graduate student studying population genetics of axolotls is currently maintaining and studying a colony of axolotls containing both dark gray and white variants. The current colony contains 750 axolotls where 237 are white and 513 are dark gray. dd D Please calculate all answers to 3 decimal places. If these axylotls are in Hardy-Weinberg equilibrium for this locus, what is the expected frequency of the recessive white allele (d)? What is the expected frequency of the dominant gray allele (D)? What would be the expected frequency of heterozygotes (Dd) in this population?

Evolutionary lineages

An evolutionary lineage is a series of populations of organisms that descend from a common ancestor. Each species in the lineage is the direct consequence of evolutionary change from a common ancestor. A phylogenetic tree is generally used to display lineages visually. Lineages are components of the phylogenetic tree of life. Molecular systematics procedures are widely used to predict lineages.
