Original sentence: For example, in another study of three-spined sticklebacks, exposure to parasite species increased MHC class IIB expression by over 25%, proving that parasitic infection increases gene expression.MHC diversity in vertebrates may also be generated by the recombination of alleles on the MHC gene.
Quantified sentence: For example, in another study of three-spined sticklebacks, exposure to parasite species increased MHC class IIB expression by a moderate amount, proving that parasitic infection increases gene expression.MHC diversity in vertebrates may also be generated by the recombination of alleles on the MHC gene.
