1. Hagrid has been breeding his creatures again. This time he is breeding Cerberus, his 3 headed dog. Having three heads is dominant over having 2 heads. He has also discovered that having chocolate brown fur is dominant to yellow fur. Hagrid crosses Cerberus (who is heterozygous for both traits) to a female that is also heterozygous for both traits. Hagrid's customers I want the super rare 2-headed, yellow furred dogs. What is the expected frequency of these dogs in the cross he conducts? Use the Punnett square below to support your answer. a) Letter that you chose to represent number of heads: b) Letter that you chose to represent the color of fur:​

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.)

One gene can influence trait(s). one trait can be determined by gene(s).

What is the difference between sex-linked traits and autosomal traits in humans? a. sex-linked traits can only be passed from fathers to sons, while autosomal traits can be passed on from both parents to offspring of any sex. b. sex-linked traits are passed on through the x and y chromosomes, while autosomal traits are passed on through the other 22 chromosomes. c. sex-linked traits only affect females, while autosomal traits affect both males and females. d. sex-linked traits refer to genes that are on the x and y chromosomes, while autosomal traits refer to genes on all 23 chromosomes.
