Lehigh University biologists demonstrate key, under-studied aspects of diploid adaptation, including that beneficial mutations that arise in diploids are not recessive, while most beneficial mutations ...

Evolution, Vol. 71, No. 2 (FEBRUARY 2017), pp. 215-226 (12 pages) Many organisms spend a significant portion of their life cycle as haploids and as diploids (a haploid–diploid life cycle). However, ...

We show that the social bees, Melipona quadrifasciata, produce a 1:1 ratio of diploid males and females by inbreeding, as is the case for Apis mellifera. However, the Apis diploid males are totally ...

Stem cell research holds huge potential for medicine and human health. In particular, human embryonic stem cells (ESCs), with their ability to turn into any cell in the human body, are essential to ...

The production of doubled haploids (DH) has become a necessary tool in advanced plant breeding institutes and commercial companies for breeding many crop species. However, the development of new, more ...
