Maize breeders is trying to determine the gene order on a metacentric chromosome. They testcross a maize plant heterozygous for three linked genes with the following recessive alleles (a,b, and d), the following phenotypes and numbers of progeny were obtained (see to right).

The genes a, b, and c, are linked on chromosome 3 in Drosophila melanogaster.

8) You just isolated a new strain of mutant mice, and preliminary mating suggest that the new mutant phenotype is not inherited in an autosomal fashion. Circumstantial evidence seems to indicate that the mutant phenotype may be following either an X-linked dominant or a mitochondrial-type inheritance pattern. Assume the mice are true breeding. a) What informative crosses would you set up to distinguish between these two possibilities? b) How would you interpret your results? 9. You are crossing two individuals...

Which of the following is a true statement? Question 9 options: A) When the map distance between two genes is small, the genes tend to be transmitted to offspring as a single unit. B) Map distances are calculated from the number of recombinant offspring. C) Map distances are determined from the results of a cross in which one parent is heterozygous, while the other parent is homozygous recessive. D) The units of map distance can be expressed as centiMorgans (cM)....

AABB and aabb individuals were crossed to each other, and the F1 generation was backcrossed to the aabb parent. 995 AaBb, 997 aabb, 3 Aabb, and 5 aaBb offspring resulted. How far apart are the a and b loci? What progeny and in what frequencies would you expect to result from testcrossing the F1 generation from a AAbb X aaBB crosss to aabb? In a typical meiosis, how many crossovers occur between genes A and B? Assume that the A...

A circular plasmid of 6.0 kB was cleaved with the restriction enzymes EcoRI, BamHI and PstI.  Cleavage with each enzyme alone gave a single band of 6.0 kB for BamHI and PstI, and a single band of 3.0 kB for EcoRI.  When BamHI and PstI were used together for the digest, bands of 1.5 and 4.5 were observed, and when BamHI and EcoRI were used together only the 3.0 kB band was observed.  What do you predict will be the pattern generated by...
