LG stands for "linkage group". It seems the Chicken Genome Sequence group (Hillier et al., 2004) allocated several linkage groups (alleles or genes which tend to be inherited together) to the microchromosomes (tiny chromosomes typical of birds and reptiles), in this case called "linkage group E64" and "linkage group E22....". There are a load more ...

If I understand you correctly, your question is why we do not see cell organelles in a cracked or boiled egg. If so, your question seems to stem ...

It seems like they are not affected by fluorescent light frequency. I did not find anything about their visual sampling rate. Their hearing is between 0-200Hz with an average of 86Hz so I guess the visual sampling rate is under this, but that's just a guess. We conclude that at the illumination levels used in this experiment, the hens did not perceive ...

The purpose of taste and smell in terms of nutrition is to determine if something is edible. If something tastes bitter or extremely sour, this is mostly a warning sign for ...

Embryonic disc forms on top of yolk during cleavage on chicken embryo, while between amniotic sac and yolk sac inside blastocyst after implantation on human embryo. Some further processes take place on and in the embryonic disc: specifically these here during the week 3. Embryonic disc formation includes still during the 3rd week of development: ...
