estion Completion Status: O c. A2A2 Od either of the one above UESTION 11 Andalusian chickens are one of the hundreds of different varieties of chickens. ( Sometime, see Feathersite.com for photographs of many more varieties of Gallus gallus.) Andalusians chickens come in 3 color varieties: black, white, and blue (so-called 'blues' are actually gray). The Black Andalusians are known to be homozygous at this color locus. We'll symbolize their genotype with: A1A1 The White Andalusian are known to be homozyogous at this color locus. We'll symbolize their genotype with: A2A2. When a Black and White are bred, all the members of their F1 are blue. you crossed two Blue Andalusians what would be the predicted genotypic ratio of their F1? If O a. 1:1 (50% blue: 50% black) Ob. 1:1 (50% blue: 50% white) Oc. 12:1 (25% white: 50% blue: 25% black) Od 2.1 (75% blue: 25% black) QUESTION 12 Andalusian chickens are one of the hundreds of different varieties of chickens (Sometime, see Feathersite com for photographs of many more varieties of Gallus gallus.)

Answer 1

Genotype of Black Genotype of white Andalusians Andalusians AIAI A2 A2 It is given that when a black & white is bred, all members of fi generation are blue. AIAL X A2 A2 A1A2 A1A2 AIA 2 ALA2 Call are blue) When a blue is are bred together A1A2 X ALA2 ΑΙΑ) AIA2 A2A! A2A2 Black Blue white So the fi generation is in the ratio 1:2:1 (25 % black, 50% blue and 25% white) so the correct answer is Optionc
