1. If two genes, A and B, are completely independent, a testcross with an individual heterozygous at both loci (AaBb) should yield what phenotypic ratios in the progeny? If the two genes are completely linked (with no recombination), what will the phenotypic ratios in the progeny be? 2. If 2 genes are linked, but not completely, what will you observe, in terms of progeny classes and numbers, when an individual who is heterozygous at both loci is crossed in a test cross? 3. If 2 genes are COMPLETELY linked, what will you observe, in terms of progeny classes and numbers, when an individual who is heterozygous at both loci is crossed in a test cross? What does it mean to say 2 genes are completely linked? 4. If 2 genes are linked, recombination results from crossovers between the chromosomes on which these two loci are located during EVERY meiotic division. TRUE or FALSE? 5. p*p b*b is the appropriate annotation to use to indicate that the p locus and the b locus are while pt b is the correct annotation to use to indicate that the p and b loci are p b+ .

1. If two genes, A and B, are completely independent, a testcross with an individual heterozygous at
both loci (AaBb) should yield what phenotypic ratios in the progeny? If the two genes are completely
linked (with no recombination), what will the phenotypic ratios in the progeny be?
2. If 2 genes are linked, but not completely, what will you observe, in terms of progeny classes and
numbers, when an individual who is heterozygous at both loci is crossed in a test cross?
3. If 2 genes are COMPLETELY linked, what will you observe, in terms of progeny classes and numbers,
when an individual who is heterozygous at both loci is crossed in a test cross? What does it mean to say
2 genes are completely linked?
4. If 2 genes are linked, recombination results from crossovers between the chromosomes on which
these two loci are located during EVERY meiotic division. TRUE or FALSE?
5. p*p b*b is the appropriate annotation to use to indicate that the p locus and the b locus are
while pt b is the correct annotation to use to indicate that the p and b loci are
p b+.
