Answer:
A. Grandmother.
B. 0
Explanation:
A. If there is no history of the disease in the family, there were only female unaffected genetic carriers. Duchenne muscular dystrophy is a recessive disease linked to the X chromosome, all man with the mutation will display the disease, since they have only one X chromosome (XY). Women have XX, so, if they inherit an abnormal dystrophin gene, but they have a normal allele on the other X chromosome, they won´t develop the muscular dystrophy.
B. The problem does not state that the woman is a carrier, so, the probability of having a child affected is zero. The disease is linked to the X chromosome, so, sons will not be affected, and daughters would have a copy of the mutated gene, but will not display the symptoms.
Similarities between gymnosperms and angiosperms:
1. They both come from the Kingdom "Plantae" and from the Domain "Eukarya."
2. They both have vascular system that are used for the conduction and distribution of water and nutrients to all the parts of the plant.
Differences between gymnosperms and angiosperms:
1. Gymnosperms are non-flowering plants whereas angiosperms are flowering plants.
2. Angiosperms have seeds that are enclosed within an ovary (it's usually in a fruit), whereas gymnosperms have no flowers or fruits. Gymnosperms have unenclosed seeds ("naked" seeds) on the surface of scales or leaves.
Temperature is what is used to measure thermal energy
<span>The more thermal energy a substance has, the more warmer it will be. So when the temperature is high, there is a lot of thermal energy </span>
<span>Thermal energy is just energy. It refers to the energy of the molecules. Temperature is just a measurement</span>
A Characteristic refers to the distinctive qualities that make up an individual. A trait, on the other hand, is a feature of an individual which is inherited. The main difference between a characteristic and a trait is while a characteristic needs to be built by a person and absorbed, a trait comes genealogically.
