a normal drosophila (fruit fly ) has both brown and scarlet pigment granules in the eyes, which appear red as a result. brown(bw) is a recessive allele on chromosome 2 that, in the homozygous condition , results in the absence of scarlet granules (so that the eyes appear brown ). scarlet (st) is a recessive allele on chromosome 3 that when homozygous, results in scarlet eyes because of the absence of brown pigment. any fly homozygous for ressive brown and recessive scarlet alleles produces no eye pigment and has white eyes. the following results were obtained from crossesp brown eyed fly * scarlet-eyed flyf1 red eyes (both brown and scarlet pigment present ) f2 9/16 red: 1/16brown :1/16 whitequestion how do I assign genotypes to the p and f1 generations and then design a testcross to verify f1 genotype and predict the results.

the scottish fold is a breed of cat with a mutation in a gene involved in cartilage development. the result is that each ear of the cat has a crease, so the ears fall forward and lie against the head instead of standing up like the ears of most small cats. the mutation is a dominant allele. a cat that is heterozygous for the fold allele mates with a cat that is homozygous for the fold allele.what are the expected percents of offspring that will have each characteristic?
