Dominant = the tall allele that "trumps" the short allele. if a dominant and recessive allele is present (heterozygous) then the dominant phenotype will be shown.

(ii) David's eyes are Brown

(iii) Sarah's eyes are blue

(iv) David - B, b

Sarah - b, b

(v) Possible genotypes include Bb and bb. These give the phenotypes of brown eyes or blue eyes.

(vi) The chance for blue eyes is 50% (or 1:1 ratio)
