(2 points) b) what is the mother's phenotype? (2 points) c) fill in the punnett square below based on the parents' genotypes. (6 points) d) describe the genotype ratio for their offspring. (2 points) e) describe the phenotype ratio for their offspring. (2 points) f) if they have a child, what is the probability of their child having wet earwax? (2 points) 2. name two processes that add to the genetic diversity of humans. (4 points) 3. a gene has the base sequence that starts with tcg gac cat cga. a) what would be the complementary dna strand formed from this dna? (3 points) b) what would be the mrna base sequence formed from this dna sequence? (3 points) c) use the codon table below to find the first three amino acids in the protein formed from this gene. (3 points) d) the gene has a mutation and is changed to the sequence below. tcg gac gat cga what kind of mutation is this? (2 points) e) what is the new mrna strand produced by this mutated gene? (3 points) f) does this mutation affect the protein produced? explain. (4 points) g) when is complementary dna produced in the body? (2 points) 4. a population of wolves migrates north in search of food. as the wolves travel, they enter a region that has long, snowy winters. some of the wolves have an allele that gives them white coats. this makes them better able to sneak up on prey. a) give two reasons that the wolf population is not at hardy-weinberg equilibrium. (6 points) b) which type of wolf is selected for in this new ecosystem? (3 points) c) how will the allele frequency change in the wolf population? (3 points) d) is this an example of natural selection? explain. (4 points) e) has genetic diversity or hurt the survival of the wolf population? explain. (4 points) 5. a large island has many different types of geography, including a large mountain area in the center. it is broken into a chain of many small islands when the ocean level rises. after the small islands form, the rate of speciation is very high. a) name three reasons that this area has a high rate of speciation, and explain each in one sentence. (9 points) b) would you expect the rate of speciation to be higher or lower for animals that cannot swim off the islands? explain. (2 points) 6. name three things that show evidence of evolution. write one sentence for each, explaining why it demonstrates evidence. (9 points) 7. a doctor is at work taking care of sick patients. she spends a few minutes trying to figure out why a particular patient is sick. she taps the patient's knee to test his reflexes. while she is examining him, the patient coughs on her. a) describe the function of the skeletomuscular system in this situation. (3 points) b) describe the function of the circulatory and respiratory systems in this situation. (3 points) c) describe the function of the immune system in this situation. (3 points) d) describe the function of the nervous system in this situation. (3 points) e) describe one way that any two of the doctor's body systems worked together in this situation.
