Q1. A dominant sex-linked gene B produces white bars on black chickens, as seen in Barred Plymouth Rock breed. A clutch of chicks has equal numbers of black and barred chicks. (Sex is determined by the Z-W system in birds: ZZ are males, ZW are females.)
a.) If only females are found to be black, what were genotypes of the parents?
b.) If males and females are equally represented in the black and barred chick; what were genotypes of the parents?
Q2. You have just created the world's first genomic library from an African giraffe. You wish to isolate the gene encoding for muscle protein, myosin, from the genomic library of the giraffe. No gene from this animal has been previously isolated as well as amino acid sequences are available in the data base. Using this information, what two strategies can you use to isolate the giraffe's gene from its genomic library?
Point out similarities and differences in their scientific foundation. What is the mainly abundant cell type? Which is the slightest prevalent.
What is estimated density of firs in the forest. Why then is the gene called Dorsal, and not, for instance, Ventral.
What are some potential research questions that would be interesting to ask of the species prepare a hypothesis and an experiment to test your hypothesis.
Plasmids, which are associated with membrane proteins, depend on bacterial chromosomal DNA for replication. If the genome contains ~30,000 genes, about how many genes would be removed by a deletion of DNA that might be detected by karyotype analysis.
While you measure the genotype frequencies of the population you get the following data. What will the frequency of Aa be in the next generation.
A patient lost a lot of blood during surgery and his blood pressure dropped from 120/80 to 90/50. Describe how the kidneys respond to this change in blood pressure.
Determine the percentage of offspring displaying each trait. If a single, diploid G2 nucleus in an ascus contains 400 nanograms (ng) of DNA, after that a single ascospore nucleus of this species should contain how much DNA (ng), carried on how many c..

What is the difference between lactococcus lactis and staphylococcus epidermis? I am doing a lab and I've found out that my bacteria are gram positive cocci that ferment lactose and mannitol. I have it narrowed down to lactococcs lactis and staphyloc..
The both endocrine and the nerve system are major regulating system of the body; however, the nervous system has been compared to an airmail system and the endoncrine system to the pony express. What is the resemblance.
Calculations must be made assuming that the minimum significant number has four significant digits. If all of phosphorus in a 3.00 gram sample of MgNH4PO4 is extracted and used to make a diphosphorus pentaoxide, what mass of P2O5 could be produced.
Explain why bacteria do not have apoptotic signaling pathways.
