Theoreticians have therefore looked for ongoing advantages of recombination
that can maintain sexual reproduction in a population . One factor that may play a
role is short - term environmental fluctuations that favor recombinant genotypes .

Although factors that favor recombination can be envisioned , it is uncertain
whether the advantage they may impart to sexual reproduction is sufficient to
counteract its twofold disadvantage . Intense selection for recombinant genotypes
is ...

Conversely , selection may favor a high copy number of genes whose product is
required in large quantities , such as rRNA , for which hundreds of genes are
carried in the genome . Models of the evolution of copy number If excess copies ...
