Chimeric mice are generated where approximately 50% of the cells in the animal are genetically MHC class I-deficient. The other 50% are deficient for the herpes virus receptor, HVEM, but do express MHC class I molecules. When these mice are infected with herpesvirus by intraperitoneal injection, a robust virus-specific CD8 T cell response is detected at day 7 post-infection in the spleens of the infected mice.

Answer:
The most likely reason some seeds are to be covered with only 1/4 inch of soil is that <u>the seeds require light to germinate.</u>
Explanation:
This seed packets does not say anyhing about temperature so we can rule out higher temperature. It is really rare to plant with seeds does not have any cotyledons and also we can't really know it from the question. Etiolation response can also be found in seedlings also from this question we can't know this for sure.
Only thing that is changes if you cover the seeds with only 1/4 inch of soil is light. If you completely cover this seed with soil it wouldn't grow.
