Answer:
A mutation that causes a single letter change in the DNA sequence can affect your protein structure and function because the sequence of letters in a gene determines the sequence of amino acids in the protein that it encodes. A single letter change in the DNA alters the mRNA which alters the amino acid sequence of the resulting protein and sometimes that can cause serious results if it changes the way a protein works.
ex. sickle cell disease - a single letter swap in the gene that encodes the hemoglobin molecule results in deformed red blood cells
Hope that helps.
Answer:

Explanation:
The genes coding for colour show codominance. Both the brown and white pigment are equally expressed in the phenotype to give the tan colour.
Considering that the allele for brown pigment is CB and that for white pigment is CW, the genotype for the brown bird is CB CB and that for the white bird is CW CW.
Crossing CB CB × CW CW,
100% CB CW - tan-coloured birds
