Complete a genetic cross to show how a fruit fly with normal wings and a fruit fly with short wings can be crossed to produce the offspring shown. (4) 11. A gene may have two or more alleles. (a) What is meant by the term allele? (1) The allele for brown eyes (B) is dominant to the allele for blue eyes (b). People with brown eyes have at least one dominant allele. (b) Complete the table. (2) eye colour alleles present brown Bb or .......... blue ..................... (c) Draw a genetic diagram to show the inheritance of eye colour in the Smith family. Show all possible outcomes. (3)
