In an clause promulgated in a late exit of the journal Molecular Biology and Evolution, she and her colleagues, including John M. Logsdon Jr., colligate prof of biota, examined the possibility that intimate procreation, piece requiring more sentence and vim than nonsexual replica, is likewise practically more park among support organisms and, thus, moldiness be real good.
The survey looked at intimate, as advantageously as nonsexual, varieties of a New Zealand freshwater escargot, Potamopyrgus antipodarum , by sequencing mitochondrial genomes and launch that the sexually reproducing snails had accrued harmful DNA mutations at almost one-half the range of the nonsexual snails.
“This is the low sketch to equate mutant accretion in a species where intimate individuals and nonsexual individuals regularly coexist, and so provides the about mastermind manifest to see that sex helps to comeback the collection of harmful mutations,” aforementioned Neiman.
Neiman plans to keep her evolutionary biota search such that a clearer agreement of the advantages of sex leave propose a ameliorate sympathy of the rate of preserving hereditary variety inside and among populations, species, and ecologic communities.
