The animal developmental program proceeds in a given precise pattern of space and time. This spatial and temporal pattern is controlled by a strikingly complex genomic regulatory system. Investigating ...

Newly emerged female offspring from the lines described above were paired with a brother in a plastic tube containing a piece of host-damaged cabbage leaf and a small droplet of honey. Observations ...

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, ...

Androgenetic haploids can be produced by holding zebrafish eggs in coho salmon ovarian fluid, irradiating them with 10,000 R of x-rays, and then fertilizing them with normal sperm. To produce diploid ...

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 ...

Researchers have been investigating the molecular mechanisms responsible for determining sex in ants. Although the vast majority of an ant colony consists of female workers, males are essential to the ...
