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…
For individual lll-6, how do you get 2/3 for the probability of heterozygous? What are the three offspring you're talking about?
In letter B: If the map distance equals the number of recombinant/total of offspring, wouldn't it be 24/806 x 100? Wouldn't we add both recombinants? Can you explain letter C? I don't grasp that concept well. And since I'm using my question already, would you be able to answer D. Thank you!

An AABB zebra fish is crossed with an aabb zebra fish. (A) is the dominant allele and (a) is the recessive allele of an autosomal gene. Similar relations exist between (B) and (b) alleles of another fish autosomal gene, at a different locus. The F1 are crossed with a homozygote recessive. a)What will be the results of the testcross and the progeny ratios if genes A and B are completely linked? b)What will the results of the testcross be if the loci assort independently? c) What will the results of the testcross be if the loci are linked with a certain recombination (crossing over) frequency?
