The extra X chromosome is received from mother.
<h3><u>Explanation</u>:</h3>
Klinefelter's syndrome is the condition of chromosomal aberration where the person has an extra X chromosome. This means the genotype of the person is 44+XXY and the total chromosome number is 47. This condition is achieved due to inappropriate meiotic division and one of the sperm or ovum has the an extra X chromosome.
Here both the parents are normal in terms of colour vision. So the father cannot have the gene of colour blindness because if it was present, then father would have been colour blind because he has only one X chromosome per cell. So its present in mother who is heterozygous in terms of colour blind gene. So the extra X chromosome also came from her which made the presence of two defective X chromosomes in the offspring and made it colour blind.
Answer:
Stop the infusion.
Explanation:
The blood transfusion can cause sometimes problem to the patient in case when the mismatched blood is given in the patient's body. Sometimes the patient body is unable to uptake the foreign blood.
As the information in the question, the RN must stop the infusion. Urticaria represents the allergy in the blood plasma protein or the immune cell reaction in the body. The infusion is prevented as this might cause the destruction of immune cells in the body.
Thus, the answer is stop the infusion.
The limitations of cell size are:
1) Surface area to volume ratio
2) Nucleo cytoplasmic ratio
3) Fragility of cell membrane
What are the cause of limitations on cell size?
The need for a surface area of sufficient area to allow the cells function→.
→If the surface area of cell increase volume increase to the cube of the linear increase.
→ Nuclie contains information needed for protein synthesis . Some cells reduce this limitation to increase the no. Of nucleus called multinucleated.
Examples are muscle cells.

To know what happens here, you need to analyze the alleles.
If the father is color blind and the daughter is not, you can suppose that is a recessive allele.
You can tell she is a carrier only, and because we received one sexual allele from each parent. If they ask you about the gender, we can suppose a cross between Xx and XY being lower x the recessive allele (color-blind vision).
When you draw the Punnett square, you'll found the probabilities are XX, XY, Xx, and xY.
So, you have a 50% chance of having a boy and 25% chance of having a color-blind boy.
