Cross is made between a pure breeding plant having red coloured flowers with a pure breeding plant having white coloured flowers. All of these offspring are red colored flower. Upon selfing of these F1 red flower plant produced both red and white flower. Which of the following is not a conclusion of these cross?

Two genes of a flower, one controlling blue (B) versus white (b) petals and the other controlling round (R) versus oval (r) stamens, are linked and are 10 map units apart. You cross a homozygous blue-oval plant with a homozygous white-round plant. The resulting F1 progeny are crossed with homozygous white-oval plants, and 1,000 F2 progeny are obtained. How many plants of each of the four phenotypes do you expect?

Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome. If a researcher moves the repressor gene (lacI), along with its promoter, to a position at some several thousand base pairs away from its normal position, which of the following results would be expected?
