-
Meitotic cell division produces _________ haploid daughter cells from each diploid parental cell.
-
Four
-
Meiosis I
-
Gametes or sperm eggs
-
None of the above

Reproduction in living things is made possible by cell reproduction when the cells break apart to form an embryo. In chapter 9 we got to cover cell reproduction and all it entails. The quiz below is the second in a series and is perfect for measuring how well you understand the process through which cells break apart to form new See morecells. Give it a try and see if you need more reading hours.

- 2.
The first haploid nuclei are produced at the end of _____________ in animals.
-
Four
-
Meiosis I
-
Gametes or sperm eggs
-
None of the above
Correct Answer
A. Meiosis IExplanation
At the end of meiosis I in animals, the first haploid nuclei are produced. Meiosis I is the first division of meiosis, where the homologous chromosomes separate, resulting in two daughter cells with half the number of chromosomes as the parent cell. These daughter cells are haploid, meaning they have only one set of chromosomes. Therefore, meiosis I is the correct answer as it accurately describes the process in which the first haploid nuclei are formed in animals.Rate this question:

The haploid daughter cells produced by meiotic cell division are called
-
Four
-
Meiosis I
-
Gametes or sperm eggs
-
None of the above
Correct Answer
A. Gametes or sperm eggsExplanation
The correct answer is gametes or sperm eggs. Meiotic cell division is a type of cell division that occurs in reproductive cells to produce gametes. Gametes are haploid cells, meaning they contain half the number of chromosomes as the parent cell. In males, the haploid gametes are called sperm, while in females, they are called eggs. Therefore, the correct answer is gametes or sperm eggs.Rate this question:

During ________ of meiosis I, homologous chromosomes intertwine, forming structures called __________
-
Prophase, crossing over
-
Chiasmata, crossing over
-
Prophase, chiasmata
-
Gametes
Correct Answer
A. Prophase, chiasmataExplanation
During prophase of meiosis I, homologous chromosomes intertwine, forming structures called chiasmata. This is the stage where crossing over occurs, which is the exchange of genetic material between homologous chromosomes. This process is important for genetic variation and the creation of genetically unique gametes.Rate this question:

Chiasmata structures are the sites of what event?
-
Prophase
-
Chiasmata
-
Prophase and chiasmata
-
Crossing over
Correct Answer
A. Crossing overExplanation
Chiasmata structures are the sites where crossing over occurs during meiosis. Crossing over is the exchange of genetic material between homologous chromosomes, which leads to genetic recombination and variation in offspring. This process occurs during prophase I of meiosis. Therefore, the correct answer is "crossing over."Rate this question:

The processes that promote genetic variability of offspring during sexual reproduction are _________, ________ and _________.
-
Meiosis I, shuffling of homologues, fusion of gametes
-
Meiosis II, fusions of gametes, chiasmata
-
Shuffling of homologues, crossing over, fusion of gametes
-
Mitosis 1, homologues, meiosis 2, crossing over
Correct Answer
A. Shuffling of homologues, crossing over, fusion of gametesExplanation
The processes that promote genetic variability of offspring during sexual reproduction are shuffling of homologues, crossing over, and fusion of gametes. Shuffling of homologues occurs during meiosis I, where homologous chromosomes exchange genetic material. Crossing over also occurs during meiosis I, where sections of homologous chromosomes are exchanged, further increasing genetic diversity. Finally, fusion of gametes occurs during fertilization, combining the genetic material from two different individuals to create a unique combination of genes in the offspring.Rate this question:
