Dark fur is dominant in pocket mice. A true breeding dark fur mouse is mated with a true breeding light fur mouse. Their F1 offspring are mated with each other. (a) What is the probability that the first three F2 offspring have dark fur? (b) What is the probability that three out of five offspring will have dark fur? (c) The phenotypes for 50 F2 mice are 30 dark and 20 light. You want to test the goodness of fit for the hypothesis that coat color in these mice is controlled by a single gene with a dominant dark allele. What is the chi-square statistic for this hypothesis? (d) What is the p-value for the above chi-square statistic? What does the p-value mean?

A mouse from a true-breeding population with normal gait was crossed to a mouse displaying an odd gait called “dancing.” The F1 animals all showed normal gait. If dancing is caused by homozygosity for the recessive allele of a single gene, what proportion of the F2 mice should be dancers if you cross two F1 mice? 25% 50% 75% 0% 33%

amSuppose you are studying a recently discovered population of rock pocket mice woth dark-colored fir that lives on volcanic rock. You take a DNA sample from a member of this new population and determine the DNA sequence of a gene known to play a role in fir color. The sequence you get is identical to that of the same gene in another rock pocket mouse population with dark-colored fur that lives on a different patch of volcanic rock. Which of...

You cross a true-breeding dark orange flowered poppy with crinkly petals to a true-breeding white-flowered poppy with smooth petals. The F1 poppies are light orange with smooth petals. In the F2 generation you get 201 orange crinkly poppies; 400 light orange smooth poppies; and 199 white smooth poppies. Explain this observation using all appropriate terminology. Also provide a breeding diagram that clearly links genotypes to phenotypes. This is all that is given.
