By what mechanism might transposons contribute to gene duplication?
a) Transposons may promote unequal crossing over during meiosis.
b) Transposon insertion may disrupt an exon.
c) Transposons may promote accidents in meiosis, leading to polyploidy.
d) Transposons cause failure of chromosomes to segregate during mitosis.
e) Transposons may lead to slippage of DNA polymerase during DNA replication.
Ans: a) Transposons may promote unequal crossing over during meiosis.
