In a chi square analysis involving genes that may be linked, which of the following statements is false?

Let’s consider two different traits in mice. A two-factor cross was made involving true-breeding mice with stubby tails and white fur to wild-type mice with long tails and black fur. All F1 offspring had long tails and black fur. The F1 offspring were then crossed to mice with stubby tails and white fur. Which of the following are the F2 recombinant offspring?

True-breeding plants with yellow/round seeds were crossed to true-breeding plants with green/wrinkled seeds. All of the F1 plants produced yellow/round seeds. The genes that affect these traits independently assort. If the F1 plants were crossed to plants that produce green/wrinkled seeds, the ratio of seed phenotypes of the F2 generation would be 

A misaligned crossover between homologous chromosomes will produce two chromosomes in which

Two genes are 36 map units apart. In a testcross, what percentage of offspring is expected to be nonrecombinants?

If two genes are linked, they do not obey

Unfortunately Phil was in a car accident and needed a blood transfusion. He was given blood type O. The young resident who ordered the transfusion panics because he didn’t give orders for Phils blood to be tested. When he did Phil was blood type AB. What is the prognosis for Phil:

With regard to linked genes along the same chromosome, which of the following statements is true?

What is the probability that this couple will have four children, three sons with short index fingers and one daughter long index fingers?

A female who is IB i has offspring with a male who IA IA. Which blood type(s) would not be possible for their offspring?
