In a type of parakeet known as a \"budgie\", feather color is controlled by two genes. A yellow pigment is synthesized under control of a dominant allele Y. Recessive homozygotes with the yy genotype homozygous do not synthesize yellow pigment. At an independently assorting gene, the dominant allele B directs synthesis of a blue pigment. Recessive homozygotes with the bb genotype do not produce blue pigment. Budgies that produce both yellow and blue pigments have green feathers; those that produce only the yellow pigment or only the blue pigment have yellow or blue feathers, respectively; and budgies that produce neither pigment are white (albino). A cross of a green budgie and a blue budgie produces offspring that are 13 green, 12 blue, 3 yellow, and 4 alb no. What are the genotypes of the parents? Oa YYBB and yyBb YyBb and YyBb O c YyBb and yyBb Od. YyBb and Yybb O e. YyBB and Ybb
Solution
Blue: yyBB, yyBb
Green: YYBB, YyBb, YYBb, YyBB
cross will create the following:a) YYBB,and yyBb which can be clearly seen in both of them blue and green
