Labradoodles are a designer dog "breed" created from the mating of a poodle with a Labrador retriever. In the first generation, labradoodles can have straight, wavy, or curly hair that is thought to be governed by two alleles at a single gene locus that show incomplete dominance. Dogs homozygous for the allele have straight hair, those homozygous for the C allele have curly hair, and heterozygotes have way hair. A labradoodle breeder has collected records for the last 10 years covering 1000 first- generation puppies. In total, 190 straight hair, 480 wavy hair, and 330 curly hair puppies were adopted. a) Calculate the frequencies of the S (p) and C(q) alleles in this population. Round your calculated frequencies to 2 decimal places. p= 1.0 q= b) The breeder suspects that her clients prefer to adopt the curly haired puppies because they are cuter. Determine whether her suspicions are correct by calculating whether the actual numbers adopted puppies for each phenotype are reflective of their expected numbers if this samples was in Hardy-Weinberg equilibrium. Enter expected numbers rounded to one decimal place. Expected number of straight-hair puppies:

Follow-up Question
Was the labradoodle breeder correct in her suspicions that curly-haired puppies
were being adopted in proportionately higher numbers given the allele frequencies
(i.e. do the numbers for each phenotype adopted reflect a population in H-W
equilibrium)? Your response should include an interpretation of the chi-square test
performed in the previous question. Please limit your response to 4 sentences.
