If two different mutant strains are said to be in the same complementation group, what does this indicate?
|
They have a mutation in the same gene |
||
|
They have mutations in different genes |
||
|
They are likely to recombine with each other |
||
|
They have complementary mutations that restore the wild-type phenotype |
Homework Answers
The answer for this question is option 2)they have mutations in different genes because ,complementation will occur only if the mutations are in different genes, in this case each strains genome supplies the wild type allele to complement the mutated allele of the other strains genome.since the mutations are recessive , the offspring will display the wild type phenotype.

46. (7 points) Vanessa has obtained two true-breeding strains of
mice, each homozygous for an
independently discovered recessive mutation that prevents the
formation of hair on the body.
One of the mutant strains is called naked, and the other mutation
strain is called hairless. To
determine whether the two mutations are simply alleles for the same
gene, Vanessa crosses
naked and hairless mice with each other (cross 1). All the
offspring are phenotypically wild-
type.

Eight mutant bacteriophage strains cannot lyse a certain type of bacteria that can be lysed by wild-type bacteriophages. The mutant strains were allowed to infect the bacteria in a complementation test. A"+ indicates that lysis occurred with coinfection. A -indicates that lysis did not occur A cistron is defined by no complementation in the configuration. How many genes are controlling lysis in this bacteriophage?

2. A yeast geneticist isolates two different haploid mutant yeast strains, Strain A and Strain B, which cannot grow unless the amino acid leucine is added to the growth media. Wild-type yeast strains can make their own leucine and do not require that it be added to the growth media. The geneticist discovers that each mutant yeast strain contains a single recessive mutation that leads to the observed leucine-requiring phenotype. When she crosses...
