Hemophilia is a sex-linked trait. A hemophilic male produces offspring with a carrier female. What are the chances that the fema

le offspring will suffer from hemophilia? What about the male offspring? Make a Punnett square to show your work.

Hemophilia is a X-linked recessive trait. I will denote it as XA for dominant and Xa for recessive.

Hemophilic male: Xa Y
Carrier female: XA Xa

Cross:

Xa Y
XA XaXA XAY
Xa XaXa XaY

Thus, as shown, of the ratio of two possible female offspring genotypes for Hemophilia, only 1/2 will have the disease; the chance is therefore 50%.

The ratio for male offspring genotypes for Hemophilia is 1/2 as well; the chance is therefore 50%.

Answer:

50% (i got it off the test)

Explanation:

Xh Y

XH XHXh XHY

Xh XhXh XhY

Females have a 50 percent chance of being hemophilic. Males have a 50 percent chance as well. All of the female offspring will carry the trait for hemophilia.

Note 1: Balanced forces do not cause alterization motion or movement. This is because of the fact that balanced forces are equal in size and in opposite directions. Consequently, this leads to cancellation and ultimately no movement.The net force for balancing forces is always 0.

Think of it this way: Take your right hand and left hand. Press them together; palm-to palm and five fingers to five fingers. Now apply equal amount of pressure (your force) as you push them in opposite directions (left hand left direction right hand right direction) Does any change in movement occur? 

Note 2: Unbalanced forces are the forces that cause change in movement and motion. When two unbalanced forces are exerted in opposite directions, the overall force (or net force) is the difference between the two forces and the direction is in favor for the larger force. 
Think of it this way. Repeat the exercise I shown you in Note 1, but this time, make apply more force in comparison to the other hand. Your right/left hand's force overpowers the weaker force of the opposite hand. The direction is in favor to your right/left hand (since they obtain the bigger force) as your hands move to the right or left side. This is an example of unbalanced forces at play.

Q22: The two forces on the left and right side are balanced given that their force is equal in size and they are in opposite directions. The two forces northwards and southwards are unbalanced forces since they are not equal in size but are opposite in direction. Recall in note 2 when I given the formula to find the net force for unbalanced forces. Its the difference (subtraction) between the bigger force and smaller force. 5 - 2 = 3. Therefore the net force for question 22 is 3.The direction is in the bigger force's direction, therefore southwards. 


Q24: Is a balanced force. Therefore the net force is 0. I don't think there is technically any direction per say.

What electrical charge is present in the balloons??
frez [133]
Usually static electricity is present in balloons when rubbing them together. There is often an imbalance of positive and negative charges in the balloons which causes the static electricity.
