What is their average life span in the wild? In captivity?
What order do they belong to?
What family do they belong to?
What is there incubation time?
Quail interphase nuclei have nucleoli with compact ___________
that stains intensely with _________ _______.
Why does this matter?
Quail cells can be distinguished from chicken cells in chimeric embryos.
The embryo is an amniote. What does that mean? What is the advantages for the study of an amniote
Early developmental pattern similar to humans.
Rapid reproductive maturation, adult are modest size, easily bred in lab, transgenic available, and fully sequenced genome.
What is Pompe's disease?
Glycogen storage disease characterized by myotonic dystrophy and acid maltase deficiency.
2 advantages of using quail to study aging
1. Hypothalamic systems exhibit neuroplasticity (aging males respond to hormone replacement therapy
2. Exhibit a bone dynamic physiology (validated model for hormone effects on osteoporosis and the role of vitamin d
T/F adults are sexually dimorphic
If T- how?
Treatment with _________ results in decreased bacterial counts, decreased foan production, and decreased fertility
What allows for prolonged sperm motility?
Cloacal gland secretes a white foamy material during copulation that can be retained by the female for more than 12 hours,
Greatest sensitivity of auditory range is?
1 - 4 kHz
Quail spend ____% of their time on ________ so should be provided with an opportunity to exhibit that behavior.
T/F the provision of perches is required
F. Quail spend little time on elevated surfaces.
T/F Quail engage in several dust bath sessions daily
T- most often in the late afternoon.
If not provided, exhibit "vacuum dust bathing" where behaviors are still expressed.
T/F captive quail can be polygamous or monogamous
T/F Males are more receptive to females when introduced in the males cage
Avian sex chromosomes are ____ & _____
Z & W
Male sex chromosomes are ____ and females are _____
For genotyping, the ________ a highly vascularized membrane in close contact with the pores of the eggshell to facilitate gas exchange, can be used to isolate genomic DNA.
Mesoderm-derived chorioallantoic membrane ( CAM)
What is inbreeding depression?
Reduces population fitness via decreased hatchability, viability, and fertility
What is the NPIP?
National Poultry Improvement Plan
Provides flock certification program to facilitate international transfer of eggs and birds.
Eggs must be stored at ______.
Storage at _____will cause embryonic cell death
Must store at 13 degrees Celsius
4 degree Celsius causes death
Name the 3 housing types
Poultry battery cages
Indoor floor pens
Semi-natural outdoor aviaries
Battery cages with sloped floors are good because they ________ ______ ______ but also result in an __________ ___________
Facilitate egg collection
Impoverished environment resulting in foot lesions, beak deformities, and bone fractures
