Question 1
You are an intern at SuperGMOpets, a biotech company producing new pets that contain genetic modifications. Their main products to date are fluorescent fishes that compete with the ones commercialized by glofish.com. While studying color in their GMO fishes, SuperGMOpets scientists have developed four alleles: P (pink), or (red), pg (green), and py (yellow). They also hypothesized that P is dominant to all the other alleles, and py is recessive to all the other alleles. The pg allele is dominant to py but recessive to pr. You have been tasked to confirm the relationships between all these alleles:
a. You cross a pure-breeding pink fish with a pure breeding red fish. Predict the genotype(s) and phenotype(s) of the progeny, and the phenotypic ratios, according to SuperGMOpetsâ€™ hypotheses.
b. You cross a pure-breeding pink fish with a pure-breeding green fish. Predict the genotype(s) and phenotype(s) of the progeny, and the phenotypic ratios, according to SuperGMOpetsâ€™ hypotheses.
c. You cross the progeny from parts (a) and (b), Predict the genotype(s) and phenotype(s) of the progeny, and the phenotypic ratios, according to SuperGMOpetsâ€™ hypotheses.
d. You cross the non-pink progeny from part (c) to a pure-breeding yellow fish. Predict the genotype(s) and phenotype(s) of the progeny, and the phenotypic ratios, according to SuperGMOpetsâ€™ hypotheses.

Question 2:
You learn that SuperGMOpets is in the process of commercializing a new kind of pet, called the yawncat. In these animals, the dominant allele R causes solid tail color, and the recessive allele r results in white spots on a colored background. The black coat color allele B is dominant to the brown allele b, but these genes can only be expressed if the animal has an mm genotype at a third gene locus. Animals that are M- are yellow regardless of which allele from the B locus is present. A mating between a solid yellow-tailed male yawncat and a solid brown-tailed female yawncat produce 16 offspring with the following tail phenotypes: six solid yellow, two spotted yellow, three solid black, one spotted black, three solid brown, and one spotted brown.
a. What are the most likely genotypes of the male and female parents? Explain the strategy used to determine the genotypes.
b. What is the probability of the next offspring having a spotted yellow tail?

Question 3:
SuperGMOpets is also trying to develop very rare, white guinea pigs. You are given two black guinea pigs from the companyâ€™s stock. You are told that these two guinea pigs are known to be heterozygous (Bb). You are also told that black fur (BB) is dominant over white fur (bb), and that a lethal recessive allele is located 2 cM (2 centimorgan) away from the recessive b allele. You are asked to produce white guinea pigs, but after mating the black-furred animals several times, you discover they produce only black progeny.
a. How would you explain this result?
b. If the original black guinea pigs produce an average of 5 offspring per mating, how many matings would you have to make before youâ€™d expect to see a white guinea pig?
c. Indicate the most likely genotype of the white offspring.

Question 4:
Finally, SuperGMOpets is aiming to bring the genetically modified micropigs craze to the US (micropig pets). Company scientists have begun to assemble a genetic map based on four recessive loci- spotty, pinkish, supertiny and playful â€“ named after the phenotypes of homozygous animals. They identified two true-breeding pigs: one is completely wild type for all loci, while the other is mutant for all four loci. They used these two pigs as parents for a P generation. The characteristics (phenotypes) of the pigs obtained at the F2 generation are summarized in the table below. Based on the following frequencies of mutant classes, determine which loci are likely to be on the same chromosome and which are the most closely linked
