  1. A pure-breeding Rat strain displays two distinct rare traits. When a male from this pure breeding mutant strain is crossed to a wild type female all the female F1 display both traits and the male F1 look wild type.
  1. What is the mode of inheritance for these traits? (1 mark)
  2. The F1 mice described above are inter-crossed to produce an F2 generation. 40% of the male F2 generation show both traits, 40% are wild type and the remaining 20% are split between displaying one trait or the other. What fraction of the female F2 progeny are expected to show both of the rare traits (2 marks)?
  3. What is the map distance (in m.u.) between the two genes specifying these rare traits (2 marks)?

You mate a male from a true-breeding strain of dwarf mice to a female from a true-breeding normal-sized strain. The F1 mice are all normal in size. What would the phenotypes of the F1 and F2 mice be in the reciprocal of the above cross if the dwarf character is caused by a mitochondrial genome defect?

Two autosomal genes control horn color in dragons. Pure-breeding gold-horned dragons were mated to pure-breeding silver-horned dragons. All of the F1 were gold. The F1 were intermated and the F2 generation consisted of 147 gold, 16 silver and 93 bronze. Conduct a chi-square test to test the appropriate type of epistasis. In the chi-square test, what is the expected number of gold-horned dragons? Round to two decimal places. Conduct a chi-square test to test the appropriate type of epistasis. In...

You are studying wing colour in butterflies. You cross pure-breeding male butterflies that have blue wings with yellow eyespots, with pure-breeding female butterflies with orange wings and black eyespots. The F1 males all have orange wings and black eyespots, while the females have blue wings and yellow eye spots. You cross the F1 males and females and obtain the following F2 (the male and female F2 give the same ratios): 90 with orange wings and black eyespots 90 with blue...

Mabari are a breed of dog native to the small country of Ferelden. Two pure-breeding mutant Mabari were crossed: The male had small ears (wild-type ears are large) and the female had purple fur (wild-type fur color is brown). All F1 dogs (male and female) had small ears and brown fur. Assuming independent assortment, what proportion of the F2 individuals are expected to be phenotypically wild type for both traits?

A female fruit fly with singed bristles was mated with a male from a true-breeding wild-type stock with long bristles. All of the F1 females had wild-type long bristles and all of the F1 males had singed bristles. If the F1 flies are intercrossed, the expected ratio of long to singed bristles in the F2 flies is Multiple Choice 3:1 in both sexes. 3:1 in females, while all the males will have singed bristles. 1:1 in both sexes. 1:1 in...

Think about the different elements of benchmarking and auditing that make these two disciplines distinct from each other. Discuss why an employee invited to participate in each of these kinds of activities might have a more favorable perspective of one over the other. What differences might drive such perception differences and what might a quality engineer do to alleviate some of the concerns raised by the more negative perceptions?
