The nurse is presenting a conference on gene dominance. What does the nurse report as the percentage of children carrying the dominant gene if one parent has a dominant gene and the other parent does not?

25%

50%

75%

100%

Answer and Explanation

The Correct Answer is B

A. If only one parent carries the dominant gene, the probability of a child inheriting it is not 25%, as this would imply a recessive-recessive pairing.

B. In a scenario where one parent is heterozygous for a dominant gene and the other has two recessive alleles, each child has a 50% chance of inheriting the dominant gene. This outcome is based on Mendelian inheritance.

C. A 75% chance would occur in a scenario involving two heterozygous parents, which is not described here.

D. 100% inheritance occurs only when one parent is homozygous dominant, which is also not indicated in this case.

Correct Answer is C

Explanation

A. Cycling can be safe during pregnancy if the woman is accustomed to it, as long as she avoids the risk of falling or injury. It is important to take precautions, but cycling itself is not inherently dangerous.

B. Swimming is an excellent form of low-impact exercise during pregnancy and is generally recommended for its cardiovascular benefits and ability to relieve physical discomforts.

C. Racquetball involves rapid movements and potential contact or falls, which could pose a risk to the pregnant woman. This activity should be avoided during pregnancy.

D. Yoga is a safe and beneficial exercise during pregnancy, especially when practicing poses that focus on flexibility, relaxation, and controlled breathing.

A. Deepening pigmentation B. Abdominal enlargement C. Ballottement D. Positive pregnancy test result

Correct Answer is A

Explanation

A. Deepening pigmentation, such as changes in the skin like melasma or linea nigra, is considered a presumptive sign of pregnancy, as it is subjective and not specific to pregnancy alone.

B. Abdominal enlargement is a probable sign of pregnancy as it is more objective and can be caused by the growing uterus. However, it may also occur due to other conditions, such as tumors or fluid accumulation.

C. Ballottement, a sensation felt when the fetus rebounds after being pushed gently, is a probable sign of pregnancy due to its reliance on the presence of a fetus.

D. A positive pregnancy test result is a probable sign because it detects hCG levels, which are strongly associated with pregnancy but may also be elevated in other conditions.
