Clonal conundrum, part deux

Posted on 24 Apr, 2015 by Stacy Krueger-Hadfield

In the second installment of the clonal conundrum, one hallmark of clonality is one that surprisingly hasn’t been validated that many times using species that have both sexually and asexually reproducing populations. Theoretically, clonal reproduction should generate massive … Heterozygote excess … Continue reading →

Haploid-diploidy, a (brief?) history

Posted on 20 Mar, 2015 by Stacy Krueger-Hadfield

Haploid-diploid life cycles are not only good exercise for the brain, but they’re also fantastic study systems to investigate a myriad of questions. Yet, the majority of molecular studies have focused on the diploid-dominated life cycles of animal and plant … Continue reading →
