Data from: Female-limited X-chromosome evolution effects on male pre- and post-copulatory success
<p>In our article, entitled "Female-limited X-chromosome evolution effects on male pre- and post-copulatory success", we carried out a female-limited X chromosome evolution experiment to study the effect of X-linked sexually antagonistic genetic variance on male reproductive traits.</p> <p>By limiting expression of the X chromosome to females for multiple generations, we removed male selective constraints, which should allow X-linked female-beneficial alleles to increase in frequency. </p> <p>As a result, expressing the experimentally evolved X chromosome in males, we found a small reduction in male fitness caused by the trade-off between male attractiveness and sperm competitiveness. These results indicate that the X chromosome in <i>D. melanogaster</i> harbors sexually antagonistic genetic variance for pre- and post- copulatory success in males.</p>
