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?
Genes A/a and B/b are linked and known to be 20 map units apart. Individuals heterozygous for both of these genes (genotypes= AB/ab) were mated with each other. Ifthere 2000 offspring from this cross, how many of the offspring would you expect to show Ab or aB phenotypes?I thought the answer was 400 but it is not.
Genes A/a and B/b are linked and known to be 20 map units apart. Individuals heterozygous for both of these genes (genotypes= AB/ab) were mated with each other. Ifthere 2000 offspring from this cross, how many of the offspring would you expect to show Ab or aB phenotypes?*AND THE ANSWER IS NOT 400!*It is not simply 20% of 2000 = 400. Please Help!
Genes A and B are 5 units apart. A doubly heterozygous female and a homozygous recessive male are crossed. Of ten thousand offspring, how many recombinant offspring would be produced? A. 2500 B. 250 C. 50 D. 500 E. 5
The A/a and B/b genes are linked and 30 map units apart. In the cross aB/Ab x aB/Ab, what fraction of the progeny will have Ab or aB phenotype?A. 48.0% B. 42.0% C. 37.5% D. 50.0% E. 45.5%
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?
If the genes A/a and B/b are on the same chromosome but 75 map units apart, , a selfed dihybrid with the genotype AB/ab would produce progeny phenotypes in theratioA. 9AB:3Ab:3aB:1abB. 1AB:1Ab:1aB:1abC. 1Ab:2AB:1aBD. 9Ab3AB:3ab;1aB E. none of the above
1) Women born with an extra X chromosome (XXX) are healthy and phenotypically indistinguishable from normal XX women. What is a likely explanation for this finding?How could you test this explanation?And can you please help me with this? PLEASE PLEASE PLEASE? I really need help.2) Assume that A and B are linked and are 50 map units apart. An animal heterozygous at both loci is crossed with one that is homozygous recessive at both loci. Whatpercentage of the offspring will...
Two genes of flower, one controlling blue(B) versus white(b) petals and the other controlling round(R) versus oval(r) stamens, are 1000 map units apart . You cross a homozygous blue-oval plant with a homozygous white-round plant. The resulting F1 progeny are crossed with homozygous white oval palnts, and 1000 F progeny are obtained . How many of each of the four phenotypes do you expect?
