Hemophilia is Xlinked recessive trait .Consider a cross between a women who is carrier and man who suffers from hemophilia, Which of the folling statements ia true

II and III

Explanation:

I. All sons of these parents will be a hemophiliac.

II. A son who suffers from hemophilia received the hemophilia allele from his mother.

III. Half of the daughters of this cross are predicted to be hemophiliacs.

Assuming the haemophilia allele is represented by h, the alternate form being H.

A woman that is a carrier will have the genotype .

A man who suffers from haemophilia will have the genotype

Crossing both of them:

  x    =  

From the result of the cross, the following can be deduced:

Half or 50% of the sons from the couple will be haemophiliacs.Any son that suffers from haemophilia received the allele from the mother.Half or 50% of the daughters from this cross will be hemophiliacs.

Hence, statements II and III are true.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
