The Biochemical Pathway For Producing A Gold Compound Is Described Below All Genes Are On Different Chromosomes Q Muta 1 (49.37 KiB) Viewed 79 times

The biochemical pathway for producing a gold compound is described below. All genes are on different chromosomes. Q mutants accumulate blue color compound N mutants accumulate tan color compound R mutants accumulate white color compound When N and Q dihybrids are crossed with each other, they produce 9 gold: 4 blue: 3 tan When N and R dihybrids are crossed with each other, they produce 9 gold: 4 tan: 3 white a.) Based on the data above, write the appropriate enzyme in the box and the appropriate color compound in the oval for this biochemical pathway in the diagram below. 369690 b.) Which gene is epistatic to N? c.) If the Q gene was a haplo-insufficient gene, from a Q and N dihybrid cross: i.) On average, what proportion of the progeny do you expect to be gold? ii.) What is the genotype of the gold progeny with respect to the Q, N, and R genes? The drawing below depicts a G1 cell. a.) Write the genotype of this G1 cell: b.) This cell is (circle 1): haploid diploid tetraploid triploid c.) How many chromosomes would be present in a G2 cell? 3 AO L -B 40 + - 89 B 7
