1. In house cats, the polydactyl trait (more than five digits on paws) is dominant to having five digits (recessive trait). A five-digit female cat was mated to a male of unknown genotype/phenotype. They had nine offspring; five of the offspring were polydactyl, while the other four had five digits.
a. From the information above, clearly indicate what the genotypes of each of the parents are. (2 marks)
b. Draw a Punnett square for this cross and indicate the genotypic and phenotypic percentages of the offspring. (2 marks)
c. If two of the polydactyl F1 offspring were crossed, what would be the expected genotypic and phenotypic percentages of this F2 generation of offspring? Draw the Punnett square for this mating. (3 marks)
1. Look at the table (right) showing survival of a group of 20 pancreatic cancer patients treated with a new drug X, compared to a control group of 20 pancreatic cancer patients who received the standard treatment and a placebo. The trial lasted for five years, which started on day 0; “lost” means that the person was lost to follow-up and did not return to the study. After 5 years everyone who was not lost to follow-up or died was known to be still alive. (20)
