Determine If Traits Are Recessive or Dominant and Autosomal or Sex-Linked

1. Is the polled trait caused by a do7minant or recessive allele? What genetic cross (or crosses) tell you the answer to this question? Explain how your experiments support your answer.

2. Is the polled allele autosomal or sex-linked? What genetic cross gave you the answer to this questions? How do your results support your answer?

3. What is another (i.e. one you did not do for the worksheet) informative cross that can distinguish between the sex-linked and autosomal possibilities in polled and Hereford cows? This cross must be different from the F1 Polled Cow x F1 Polled Bull cross in Question 4b. Describe your cross and indicate how it distinguishes between autosomal and sex-linked alleles.

4. In fruit flies, is the orange eye mutant allele dominant or recessive to wild type? Describe the cross that gave you the answer and explain how the cross tells you the answer.

5. Are the orange and white eye phenotypes caused by alleles of the same gene? Or are they alleles of two different genes? Describe the cross that tells you the answer to that question and explain how the cross tells you the answer.

6. Is the orange mutation on an autosome? Or is it sex-linked? explain how you figured this out.

7. Is the white mutation on an autosome? Or is it sex-linked? explain how you figured this out.
