utations in both genes, with a mutated factor VIII allele on one X chromosome, and a mutated factor IX allele on the other. All of her sons should have either hemophilia A or B. However, on rare occasions, one of these women gives birth to a son who does not have hemophilia, and his one X chromosome does not have either mutated allele. Explain.

Marat540 [252]

Answer:

3 North poles and 3 South poles

Explanation:

A magnet is a piece of object that produces a magnetic field outside itself. A magnet has a north pole and a south pole. Similar poles repel each other, while opposite poles attract each other.

If a magnet of 10cm is broken into 3 pieces, we will have 3 pieces of magnet. Breaking a magnet does not destroy the properties of the magnet. Rather, each piece becomes a full magnet with both north and south poles.

Breaking a 10cm magnet will give us 3 magnets with 3 north and 3 south poles with equal pole strength.
