Intragenic recombination can be detected __________.
A)based on recombination between homologs carrying different mutant alleles
B)by the recovery of 100% double-mutant chromosomes
C)by the recovery of both wild-type and double-mutant chromosomes
D)based on recombination between homologs with different mutant alleles and recovery of 100% double-mutant chromosomes
E)based on recombination between homologs with different mutant alleles and recovery of both wild-type and double-mutant chromosomes

Question

Quizplus · Accepted Answer

Intragenic recombination occurs within a single gene on the same chromosome. It can be detected by the recovery of both wild-type and double-mutant chromosomes, as the result of recombination between homologs with different mutant alleles. Recovery of 100% double-mutant chromosomes alone would indicate that the mutants are in different genes or on different chromosomes. Recovery of both wild-type and double-mutant chromosomes indicates that intragenic recombination has occurred within the same gene on the same chromosome.
