Answer:
One-half of the daughters of an affected man would have this condition.
Explanation:
Each daughter born to a woman that is positive for a dystrophin mutation on one of her two X chromosomes possess a 50 percent likelihood of possessing the mutation and also becoming a carrier. Carriers at times do not show the disease symptoms but may give birth to a child that has the mutation or the disease condition. DMD carriers do have a higher chance of cardiomyopathy.
A man with DMD cannot transfer the affected gene to his sons since he passes to his son a Y chromosome, not the X chromosome. But he will definately transfer it to his daughters, since each daughter possess her father’s only X chromosome resulting in the daughters being carriers.
Hence, One-half of the daughters of an affected father and a carrier mother could have this condition.

<u>Without a water supply, organisms in aquatic and land habitats will die. Organisms without access of water cannot access oxygen, and as a result of that, they would die. Oxygen is needed for organisms in order to survive. Water also helps insulate the living environment for these organisms.</u>
At the place marked with the letter A we have a divergent plate boundary. On this type of boundary, the plates are moving away from one another. As they move away, they leave a gap behind them, and the crust is becoming thinner and thinner with lots of cracks in it. Because of that, the high pressures from the mantle manage to push upwards the magma with ease. The magma reaches the seafloor and it is pushing the crust upwards until it breaks it. As the magma pushes the crust upwards,underwater volcanoes are formed, and when the crust is broken by the magma, the magma flows get on the seafloor, cool of very quickly in the water, and create new crust.
