In the "P" generation, you cross two true-breeding flies. The female parent is brown and wingless and the male parent is black with normal wings. All of the flies in the F1 generation are brown and have normal wings. Indicate the alleles associated with dominant phenotypes by uppercase letters and alleles associated with recessive phenotypes by lowercase letters. Assume the genes are not found on a sex chromosome. Indicate the color alleles as "B" and "b" the wing alleles by the letters "N" and "n". a) The genotypes of the flies in the P generation are: female and male. b) The genotype of the flies in the F1 generation is: c) You now take an F1 female and cross her to a true-breeding black, wingless male.

In a population of cats every male cat is either orange or black and females are either orange, black or tortoise shell (heterozygotes with genotype XOX+). In this population, 15% of the male cats are orange. What is the frequency of the orange allele (X) in this population? (Please round all answers for this question to 3 decimal places) Assuming this population is at Hardy-Weinberg equilibrium for coat color, what proportion of females would be predicted to have a tortoise shell coat?

- Question 5 You are studying a species of tree frog with skin that produces different toxins based on the genotype of the Tox locuS. Alleles E and N are codominant. Individuals homozygous for E are emetic (eating them causes vomiting), while individuals homozygous for N produce a neurotoxin. Heterozygotic frogs produce a toxin with both qualities. At the La Selva Biological Station in Costa Rica, you collect frogs from the field site and test them in the lab. You find 93 neurotoxic frogs, 113 emetic frogs, and 12 frogs with both toxic qualities. Using the Hardy-Weinberg equilibrium equation, what are the expected numbers of frogs given their genotypes at the Tox locus? 45 NN, 108 NE, 65 EE B 93 NN, 12 NE, 113 EE 324 NN, 446 NE, 154 EE D) 198 N, 238 E Last saved 1. 67 minutes remaining P Type here to search Home DII PrtScn F8 F6 F7 F3 F4 F5Question 10 In a population of mountain lions, 9% of the individuals suffer from a disease caused by a recessive allele (aa).

- QUESTION 3 You performed a Genome-Wide Association Study (GWAS) attempting to link genotypes to the likelihood of having Disease X. You found that the Odds Ratio for those with Genotype A relative to Genotype B for having Disease X to be equal to 3. How would you best describe the risk of having Disease X with Genotype A compared to Genotype B? A Equal risk for Disease X with Genotype A B. Less risk for Disease X with Genotype A OC.

QuQuestion 20 You are studying a species of butterfly whose caterpillars produce different toxins based on the genotype of the Tox locus. Alleles E and N are codominant. Individuals homozygous for E are emetic (cause vomiting), while caterpillars homozygous for N produce a neurotoxin. Heterozygotic caterpillars produce a toxin with both qualities. At the Bocas del Toro research station in Panama, you counted 45 neurotoxic caterpillars, 57 emetic caterpillars, and 82 caterpillars with both toxic qualities.
