Imagine the autosomal dominant cb allele produces black coat color in dogs, and the recessive cw allele produces a white coat color. the cb allele is also recessive for lethality; pups with the cbcb genotype die well before birth, and their remains are resorbed by the mother’s uterus. imagine you cross a heterozygous black male dog with a heterozygous black female. what ratio of genotypes and phenotypes do you expect to see in the f1 offspring? if more than one genotype produces the same phenotype, list all the genotype/phenotype combinations separately.

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations. for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)
