Question

Offsprings formed as a result of sexual reproduction exhibit more variations because

• A. Sexual reproduction is a lengthy process.
• B. The genetic material comes from two parents of different species.
• C. The genetic material comes from two parents of same species.
• D. The genetic material comes from many parents.

Answer 1

The correct option is C

The genetic material comes from two parents of same species.

The correct option is C.

Explanation of the correct option:

1. The genetic material used in sexual reproduction is derived from both parents.
2. Because the genetic makeup of the two parents is that of the same species, this explains why there are variations in the children.
3. The variation also happens during the meiotic process of crossing over, which is responsible for the production of gametes by rearranging the genetic material.

Explanation of the incorrect option:

Option A:

1. Sexual reproduction is a time-consuming procedure.
2. Parents' gametes have a qualitatively diverse genetic composition.
3. A bigger amount of DNA is involved in sexual reproduction since it comes from parents of two different species.
4. But that will not result in variations.

Option B:

1. Sexual reproduction is the process by which two individuals of the same species contribute two distinct gametes, one male and one female.
2. Hence, the genetic material comes from two parents of different species which will be incorrect.

Option D:

1. Sexual reproduction is the process by which two individuals of the same species contribute two distinct gametes, one male and one female.
2. The mixing of genetic material occurs as a result of gamete fusion, and a diploid cell with the new combinations is created.
3. Hence, the genetic material that comes from many parents is incorrect.

Final answer: Offsprings formed as a result of sexual reproduction exhibit more variations because the genetic material comes from two parents of the same species.
