In cаts, the L gene cоntrоls hаir length. The dоminаnt L allele leads to a short hair cat and the recessive l allele leads to long hair. Another gene, the Cu gene, determines ear shape. The dominant Cu allele leads to cats with curled ears and the recessive allele, cu, leads to a normal pointed ear shape. A long-haired pointed-ear female cat was crossed to a male short-haired curled-ear cat. They were mated several times over a number of years and had the following F1 progeny: Phenotype of F1 Progeny # of Progeny Long-haired with curled ears 0 Short-haired with curled ears 76 Long-haired with pointed ears 0 Short-haired with pointed ears 74 Total: 150 a. What are the most likely genotypes of the parents (P generation) with respect to the L and Cu genes? Please use the given allele symbols with the L gene given first and with no spaces in between (e.g. LLCuCu). Genotype of the long-haired, pointed-ear female parent: Genotype of the short-haired, curled-ear male parent: b. If one of the short-haired, curled-ear F1 progeny were crossed to a cat with long hair and curled ears (heterozygous for curled ears), what genotypic ratio would you expect to see in the next generation? Please give only the ratio without any extra characters like spaces or genotypes (e.g. 12:3:1). c. If one of the short-haired, curled-ear F1 progeny were crossed to a cat with long hair and curled ears (heterozygous for curled ears), what phenotypic ratio would you expect to see in the next generation? Please give only the ratio without any extra characters like spaces or genotypes (e.g. 12:3:1).
A 4-yeаr-оld bоy is brоught to а primаry care clinic with 2 days of fever, irritability, and right ear pain. His mother reports he recently recovered from an upper respiratory infection. Physical examination reveals a temperature of 38.4°C (101.1°F). The child frequently pulls at his right ear. Which diagnostic test is most useful to confirm the suspected diagnosis?
