Suppose a point mutation, such as a change from an adenine to a guanine, occurs in the genome of a human sperm cell. the mutation could occur in any region of a gene. the effect of the mutation on the phenotype of the offspring will be determined by where the mutation occurs and its effect on the final gene product. in which of the following scenarios could the mutation alter the phenotype of the offspring? select all of the scenarios that apply the mutation occurs in the promoter and affects the rate of gene transcription. the mutation results in a new, dominant allele the mutation occurs in a portion of an intron not responsible for exon splicing the mutation occurs in a gene that controls development and alters differentiation of a cell type during development. the mutation occurs in a codon and alters the function of the final protein e mutation occurs in a codon, and the amino acid sequence of the final protein is unchanged.

Finches living on the galapagos islands were critical for darwin to develop his ideas. what key observation did he make about the finches? a. the finches' feathers were structurally different to allow them to fly at different heights and speeds, depending on their local environment. b. the finches' beaks were uniquely adapted as tools for them to eat the food that was available to them. c. the finches' feathers were colored differently, providing camouflage within their unique environment. d. the finches' beaks were colored differently, providing camouflage within their unique environment
