Answer:
1/2
Explanation:
Let's assume that the allele "p" is responsible for PKU in the homozygous state. According to the given information, both the parents are unaffected by the disorder but have an affected child. This means that both the parents carry at least one copy of the recessive allele responsible for the disease. Therefore, the genotype of each of the parents is Pp. A cross between Pp and Pp would produce progeny in following ratio=
Pp x Pp = 1/4 PP: 1/2/ Pp: 1/4 pp
Therefore, the probability that their next child will carry just one recessive allele is 1/2.
Because there are too many sex chromosomes I think
Answer:
DNA is located inside the nucleus (There is also a small percentage of Dna inside the mitochondria)
<span>Digoxin toxicity is a poisoning that occurs in people due to excessive intake of the medication digoxin or the consumption of plants such as foxglove and lily of the valley that contain digoxin. Manifestations for digoxin toxicity that the nurse should monitor for before administering this medication are vomiting, loss of appetite, confusion, blurred vision, arrhythmias, decreased energy, and irregular heartbeat. The nurse should also closely monitor the electrolyte levels because low levels of potassium and magnesium increase the risk for digoxin toxicity. If digoxin is administered, the heart rate should be counted before every dosage. If the heart rate is lower than 60 beats per minute, the drug should be stopped and the health care professional should be notified.</span>
