Repair of heteroduplex regions formed during recombination can result in a 1:3 or 3:1 segregation of parental alleles, which indicates that ________ has occurred.
A)allelic exchange
B)gene conversion
C)crossing over
D)recombination
E)DNA replication

Question

Quizplus · Accepted Answer

Gene conversion is the process responsible for the 1:3 or 3:1 segregation of parental alleles following the repair of heteroduplex regions formed during recombination. This non-Mendelian segregation pattern occurs when the genetic material from one allele is copied over another, leading to an unequal representation of the original parental alleles.
