f.
Impossible to know without more information.
Solution
As we know that an X-linked dominant inheritance is a kind of genetic condition in which X linked mutant is a dominant trait. Thus, even if one copy of X chromosome is present, the offspring would be diseased individual.
Here , Given
Woman has ip, hence in order to have unaffected girl child she must mate a normal man
Genotype of woman would be XX'
Genotype of man would be YX
XX' * YX
XY, XX, X'Y. X'X
Two daughter and two son will be produce.
Out of the two daughters one is diseased and another one is normal.
Thus, the chance that newborn will be an unaffected girl is
![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Thus, option A is correct
On performing CPR on a 3-year-old child while your partner prepares the AED. The compression to ventilation ratio should you be providing is 30:2.
30:2 should be the compression to ventilation ratio, on performing CPR on a 3-year-old child while your partner prepares the AED.
30:2 means that the Compression should be 30 on the chest with 2 ventilations in the compression.
CPR or Cardiopulmonary Resuscitation is an emergency procedure to compress the chest by artificially ventilating to save the patient to rejuvenate the blood the circulation.
AED is Anautomated External Defibrillator.
It is a lifesaving procedure to save the child who suffered from cardiac arrest or heart attack.
It can be performed for up to 30 minutes and can be stopped if the circulation does not continue even after that.
It is better to remove the clothing of the child to perform the CPR to avoid any harm.
