James should be given an Oxygen 100% for 15 to 30 minutes. Preventative therapy for cluster headaches includes Ergotamine nightly before bed. Cluster headaches are a series of relatively short but extremely painful headaches every day for weeks or months at a time. You tend to get them at the same time each year, such as the spring or fall. Because of their seasonal nature, people often mistake cluster headaches for symptoms of allergies or business stress.

Colored aleurone in the kernels of corn is due to the dominant allele R. The recessive allele r, when homozygous, produces color

Pie

Answer:

The genes are linked, and the arrangement is coupled (one homolog has both dominant alleles; the other homolog has both recessive alleles).

RY / ry

Explanation:

R_= colored aleurone

rr= colorless aeurone

Y_= green plant

yy= yellow plant

They do a testcross between a plant of unknown genotype and phenotype and a plant that is homozygous recessive for both traits (yr/yr) the following F1 is obtained:

88 Colored, green (RY/ry)
92 colorless, yellow (ry/ry)
8 colorless, green (rY/ry)
12 colored, yellow (Ry/ry)

If the genes assorted independently, all of the possible offspring phenotypes would appear in the same frequency. However, they obtained 2 phenotypes much more abundant that the other two. Since recombination is a rare event during crossing over, when two genes are linked the recombinant gametes are produced less frequently than the parentals.

We can propose that the phenotypes Colored, green (RY) and colorless yellow (ry) are the parental gametes, and the unknown plant has the arrangement RY/ry, with both genes linked.
