Parts a-c of this question address the crossing of parents with the following genotypes: A/a; B/b; C/c; D/d; E/e; F/f                       x          a/a; b/b; c/c; d/d; e/e; f/f a. What is the probability that an F1 progeny that is homozygous recessive at every locus will be produced? For values greater than 0, please answer as a fraction.  b. What is the probability that an F1 progeny that is homozygous dominant at every locus will be produced? For values greater than 0, please answer as a fraction. c. Would one of the parents in this cross be considered a test cross parent (tester)?  Yes, the parent on the left, with genotype A/a; B/b; C/c; D/d; E/e; F/f would be the test cross parent (tester). Yes, the parent on the right, with genotype a/a; b/b; c/c; d/d; e/e; f/f would be the test cross parent (tester). Yes, both parents would be considered a test cross parent (tester) No, neither parent would be considered a test cross parent (tester) None of the above and I have explained my reasoning here:

Parts a-c of this question address the crossing of parents with the following genotypes:

A/a; B/b; C/c; D/d; E/e; F/f                       x          a/a; b/b; c/c; d/d; e/e; f/f

a. What is the probability that an F1 progeny that is homozygous recessive at every locus will be produced? For values greater than 0, please answer as a fraction. 

b. What is the probability that an F1 progeny that is homozygous dominant at every locus will be produced? For values greater than 0, please answer as a fraction.

c. Would one of the parents in this cross be considered a test cross parent (tester)? 

  1. Yes, the parent on the left, with genotype A/a; B/b; C/c; D/d; E/e; F/f would be the test cross parent (tester).
  2. Yes, the parent on the right, with genotype a/a; b/b; c/c; d/d; e/e; f/f would be the test cross parent (tester).
  3. Yes, both parents would be considered a test cross parent (tester)
  4. No, neither parent would be considered a test cross parent (tester)
  5. None of the above and I have explained my reasoning here:
