5 Figure 5.1 (see аddendum Questiоn 5) shоws а speckled chicken. These chickens hаve a mixture оf black and white feathers. 5.1 The colour of the feathers of a chicken is an example of codominance. One parent of this speckled chicken had white feathers and the other parent had black feathers. Describe the difference between each of the following pairs of terms, using feather colour to illustrate your answer. 5.1.1 Gene and allele (3) 5.1.2 Genotype and phenotype (3) 5.2 A black chicken was mated with a speckled chicken. They had 25 chicks. Determine the expected number of speckled chicks. You must use a genetic diagram. (3) 5.3 Most Bengal tigers are orange with black stripes but there is a very small number of Bengal tigers that are white with black stripes. Figure 5.3.1 (see addendum Question 5) shows a white Bengal tiger with black stripes White tiger offspring are produced by two Bengal tigers that each carry at least one recessive allele for a gene affecting coat colour. The pedigree diagram 5.3.2 (see addendum Question 5) shows the phenotypes in one family of tigers, bred in captivity. 5.3.1 State the probability that the next tiger born to these two parents will be female. (1) 5.3.2 Determine the expected phenotypic ratio of orange tigers to white tigers born to the parents shown in this pedigree diagram. Use a genetic diagram to support your answer. (3)
