Colour vision deficiency is an x-linked recessive disorder. A female whose father has colour vision deficiency has normal vision. What is her genotype?

In a new variety of cat, the Pastel cat, pink fur color is dominant to sky blue fur. A pink cat was crossed with a blue cat and produced three kittens. One was blue and two were pink. 

One of the two pink kittens wandered off and was later found sleeping next to the neighbor's dog. (The neighbor also has Pastel cats and thinks that the kitten was playing with one of her kittens.) A DNA test was performed on the lost kitten (for different reasons) and the kitten was discovered to have two dominant alleles. (PP) 

What are the genotypes of the parents?

Did the neighbor return the correct kitten? Explain your answer

Research the strengths and weaknesses, advantages  and disadvantages of the genetic technologies explored in the relevant unit content. All sources consulted will be accurately referenced. They must use the research to support their own views, speculating in an informed manner about future uses of generic engineering technologies. They must provide counterarguments of the reliability and validity of the use of the technologies.  

analyse the use of genetic technologies in relation to industry and/or medicine. The analysis will take into account the reasons and science behind the technologies, benefits to the relevant sector of industry or medicine, and include an appreciation  of efficacy and cost. This may be achieved effectively through the detailed examination of one  real-life example for each technology.
