5. Deletions can be used to map genes along a chromosome. In order to do this a series of crosses in which one parent is homozygous for a mutant allele is crossed with the other parent that is homozygous for a partial deletion of the region. The progeny are scored to determine whether they have the mutant phenotype ("m") or the wild-type phenotype ("+"). If the mutant allele falls within the deletion it will have the "m" phenotype, if it...
The B and N genes are 25 map units apart on a chromosome. a) Following a dihybrid testcross, how many offspring of 250 would you expect to display a recombinant phenotype? a) If you performed a dihybrid testcross, with a cis dihybrid, what would be the genotypes of both recombinant offspring phenotypic classes?
Excluding chromosome aberrations, the order of genes on a genetic map of a chromosome is the same as on its physical map. Why are the distances different?
In flamingos, genes A and B are known to be 21 map units apart on chromosome #5. You mate an AA:BB male with an aa:bb female to produce F1 flamingos. a. What gametes will be made by these F1 individuals and in what proportions? b. When the F1's are bred to each other, they produce a total of 276 offspring. How many of these offspring would you predict should have the genotype Aa:BB?
Suppose the F and G genes are on the same chromosome and separated by 75 map units What fraction of the progeny from the cross FG/fg times fg/fg are expected to be Fg/fg? 12.5% 50% 25% 37.5% Two genes cannot be separated by 75 map units.
Genes A and B are located on the same chromosome 10 centimorgans apart. What is the likelihood of AB/ab progeny in a cross between Ab/aB and ab/ab individuals? a. 1/20 b. 1/10 c. 1/4 d. 9/20 e. 9/10
5. In humans, if two genes are 28 CM apart on the same chromosome, what percentage of gametes would you expect to be recombinant with respect to these two genes? Show your work. (9 points)
The following map indicates the order of three genes (A, B, and C) on a chromosome and the number of map units between adjacent gene pairs. What is the expected frequency of the gametes ABC and abc produced by an individual of genotype AbC//aBc. (Assume no interference.) A---->8 m.u.--->B --->24 m.u.--->C 0 69.92% O 0.96% 06.08% 1.92% 022.1%
