pure breeding white budgies were crossed with pure breeding yellow and green budgies. all the F1 offspring were yellow and green. the F1 was then testcrossed with pure breeding white budgies, and the offspring were as follows:

Green and Yellow 25
White 27
Blue and White 23
Yellow and White 24

Explain these results using symbols and statistics. Provide the genotypes of the parents, F1 and progeny from the testcross and
corresponding phenotypes (5 marks)
