About This Quiz
Reproduction is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction.

- 2.
Male has ___________ chromosomes.
-
XX
-
XZ
-
XY
-
Option 4
Correct Answer
A. XYExplanation
In humans, males have XY chromosomes. The presence of the Y chromosome determines male development, while the absence of the Y chromosome results in female development. Therefore, the correct answer is XY.Rate this question:

In asexual Reproduction, an organism produces another organism which is identical to itself
-
True
-
False
Correct Answer
A. TrueExplanation
In asexual reproduction, an organism has the ability to produce offspring that are genetically identical to itself. This means that there is no genetic variation or combination of genes from two different parents. Instead, the offspring are clones of the parent organism. This process commonly occurs in single-celled organisms, such as bacteria, as well as in some plants and animals. Asexual reproduction is an efficient way for organisms to rapidly increase their population size, as they do not have to rely on finding a mate or going through the complex process of sexual reproduction.Rate this question:

Human fertility rate is at its peak in human history currently.
-
True
-
False
Correct Answer
A. TrueExplanation
The statement suggests that the current human fertility rate is the highest it has ever been in history. This implies that more people are able to reproduce and have children now compared to any other time in the past. This could be due to various factors such as advancements in healthcare, better access to contraception, and improvements in overall living conditions. However, without additional data or context, it is difficult to determine the exact reasons behind this peak in fertility rate.Rate this question:

A fertilized egg passes through the _______ tubes from the ovaries of female mammals to the uterus.
Correct Answer
FallopianExplanation
The correct answer is Fallopian. The question asks for the name of the tubes through which a fertilized egg passes from the ovaries to the uterus in female mammals. These tubes are called the Fallopian tubes.Rate this question:

Crossing over takes place in
-
Mitosis
-
Meiosis
-
Option 3
-
Option 4
Correct Answer
A. MeiosisExplanation
Crossing over takes place in meiosis. During meiosis, which is a type of cell division that produces gametes, crossing over occurs in the prophase I stage. Crossing over is the exchange of genetic material between homologous chromosomes, resulting in genetic recombination. This process contributes to genetic diversity by creating new combinations of alleles and increasing the variability of offspring. In contrast, crossing over does not occur in mitosis, which is a type of cell division that produces identical copies of cells for growth and repair.Rate this question:

Haploid cells have two sets or 2(n) number of chromosomes
-
True
-
False
Correct Answer
A. FalseExplanation
Haploid cells actually have only one set or n number of chromosomes, not two sets or 2(n) number of chromosomes. This is because haploid cells contain only one complete set of chromosomes, which is half the number found in diploid cells. Therefore, the given statement is false.Rate this question:

The cell begins to divide in
-
Interphase
-
Prophase
-
Metaphase
-
Anaphase
Correct Answer
A. ProphaseExplanation
During prophase, the first stage of mitosis, the cell begins to divide. This is characterized by the condensation of chromatin into visible chromosomes, the breakdown of the nuclear membrane, and the formation of the mitotic spindle. These events prepare the cell for the subsequent stages of mitosis, including metaphase, anaphase, and telophase. Therefore, prophase is the correct answer.Rate this question:

Variation occurs in ___________
-
Meiosis
-
Mitosis
-
Anaphase
-
Telophase
Correct Answer
A. MeiosisExplanation
Variation occurs in meiosis. Meiosis is a type of cell division that occurs in sexually reproducing organisms. During meiosis, the genetic material is shuffled and recombined, leading to the creation of genetically diverse offspring. This genetic variation is important for evolution and adaptation to changing environments. In contrast, mitosis is a type of cell division that produces genetically identical daughter cells. Anaphase and telophase are stages of mitosis, and although they involve the separation of chromosomes, they do not contribute to genetic variation in the same way as meiosis.Rate this question:
