Question

Identify from the following an incorrect statement with reference to sexual reproduction.
A. It involves fusion of units called gametes.
B. It involves only one parent.
C. It is the most common type of reproduction in animals.
D. It involves meiosis type of cell division.

Answer 1

Hint: Sexual reproduction is the type of reproduction in which the gamete combines with haploid and forms an organism. It can be found based on the reproduction. Here, in the type of reproduction that is sexual reproduction the incorrect one which does not come under sexual reproduction can be found and analyzed.

Complete answer:
Reproduction is the kind of biological process by which new individuals are produced. It is a fundamental feature of all known life that exists as a result of reproduction. This is of two types. They are:
-Asexual reproduction.
-Sexual reproduction.
The example for reproduction is green algae. They are also called plus and minus gametes.
Here we are going to see only about sexual reproduction,
-SEXUAL REPRODUCTION:
Sexual reproduction is a type of reproduction which involves a complex life cycle in which a gamete containing a single set of chromosomes combines with another and produces two sets of chromosomes.
-ADVANTAGES:
-It produces genetic variation in offspring.
-These species can adapt with new environments due to variation which gives survival advantage.
-This is a disease that likely affects the population.
DISADVANTAGES:
-When two individuals get involved, fusion is difficult.
-Population growth will be slow.
-Some of the variations may have undesirable qualities.
SIGNIFICANCE:
-Variation
-Vigor
-Evolution
-Vitality
-Uniformity of population.
So, the correct answer is “Option B”.

Additional Information: This is the most common lifecycle in some of the multicellular eukaryotes like animals, fungi and plants. It does not occur in prokaryotes but processes with similar effects such as transformation and transduction. This also includes the process of meiosis and mitosis and also allogamy and autogamy.

Note:
This type of reproduction is morphologically distinct with two cells. They include ovum and sperm. And they are created with the cell division called meiosis. This is the most common type of reproduction that involves two parents.
