A human protein, MC1R is responsible for telling human cells what type of pigment proteins to produce. One version of MC1R causes cells to make red pigments, while another version causes our cells to make black pigments. The red version causes red hair. The black version causes black hair. How did these 2 versions come to exist? gene flow mutation natural sclection genetic drift

Neanderthal Hair Color The MCIR gene regulates pigmentation in humans (Sections 14.1 and 15.l revisited), .so loss-of-function mutations in this gene affect hair and .skin color. A person with two mutated alleles for this gene makes more of the reddish melanin than the brownish melanin, resulting in red hair and pa le skin. DNA extracted from two Neanderthal fossils contains a mutated MC1R allele that has not yet been found in humans, To see how the. Neanderthal mutation affects the function of the MC1R gene, Carles Lalueza-Fox and her team introduced the allele into cultured monkey cells (FIGURE 26.1 6). FIGURE 26.16 MC1R activity in monkey cells transgenic for an unmutated MClR gene, the Neanderthal MC1R allele or the gene for green fluorescent protein (GFP). GFP is- not related to MC1R. 2. What does this imply about the mutations effect on Neanderthal hair color?

Background: In class we did a project about m and m’s and there ability to evolve and natural selection. (Yes I know they can’t actually evolve it was just used as a example in class) however I can’t figure out this question. Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________. What goes in the blank
Suppose that a gene has a mutation that changes one nucleotide. Compared to the protein produced from the non-mutated gene, this new protein contains a stop codon where an amino acid was previously found in the original version. This type of mutation would be classified as a frameshift mutation. degenerate mutation. silent mutation. missense mutation. O nonsense mutation. 身
