Introduction:
The reproduction can be defined as the process through which the living organisms produce new offspring. One of the fundamental features of life is reproduction. There are two different forms of reproduction, namely- asexual reproduction and sexual reproduction.
Answer to Problem 1MCQ
Correct answer:
The unique feature of the sexual reproduction is its ability to produce different genetic combinations. Therefore, option (c) is correct.
Explanation of Solution
Reason for the correct statement:
The sexual reproduction involves two different parents. Each of the parents produces gametes, which are formed by the process known as meiosis. The gametes fuse to form a zygote. The genetic characteristics of the zygote are the combination of both the parents. Unlike, in asexual reproduction, where the offspring are genetically identical to the parent as well as siblings, the offspring in sexual reproduction are genetically different.
Option (c) is given as “the ability to generate new genetic combinations”.
As, “the offspring are formed by the fusion of the male and female gamete, the sexual reproduction leads to the production of new genetic combinations”, is the right answer.
Hence, option (c) is correct.
Reasons for the incorrect statements:
Option (a), is given as “the ability of a cell to divide”.
The cell division can take place through the asexual reproduction. Hence, it is a wrong answer.
Option (b), is given as “the production of offspring”.
The offspring are also produced by the asexual reproduction also, so it is not a unique feature of sex. Hence, it is a wrong answer.
Option (d), is given as “all of the above are correct”.
The cell division and the production of offspring can take place through the asexual reproduction also. Hence, it is a wrong answer.
Hence, options (a), (b), and (d), are incorrect.
The sexual reproduction involves the fusion of male and female gametes, which are formed by the process of meiosis. So, the genetic characteristics of the zygote formed by the sexual reproduction are combination of the characteristics of both the parents.

- Binary fission is a form of asexual reproduction. What is an advantage of asexual reproduction when compared to sexual reproduction? a Asexual organisms are less likely to have mutations in their DNA than sexual organisms are. b An organism that reproduces asexually can reproduce much more quickly than an organism that reproduces sexually. c An asexual organism lives longer than an organism that reproduces sexually. d An organism that reproduces asexually is better equipped to respond to environmental changes than an organism that reproduces sexually.arrow_forwardCompare and contrast sexual and asexual reproduction. Identify the most accurate statement. a. Asexual reproduction results in more offspring per mother. b. Sexual reproduction is always more costly. c. Sexual reproduction is associated with an increase in homozygosity. d.

- Which of the following statements does NOT correctly describe the similarities and differences between male and female reproductive systems? Select one: a. Millions of mature sperm are produced on a daily basis, whereas single mature ovum is released every 28 days. b. Meiosis is completed in eggs after fertilization begins, whereas a mature sperm has completed meiosis prior to fertilization. c. Eggs and sperm contain exactly half of the genetic material of a normal somatic cell. Many zygotes with an abnormal number of genetic material often do not successfully implant. d. Eggs and sperm can survive for 3 to 5 days in the Fallopian tubes.arrow_forwardWhy is parthenogenesis in bees considered to be a form of asexual reproduction? Select one: a. The male drone is made from a haploid egg. Fertilization is not part of the process to make a male drone. b. The formation of the original haploid cell was achieved using binary fission. c. Although genetic material is transferred from one cell to another using conjugation, the resulting cells will be identical to each other. d. The haploid male bees were made through the process of meiosis, so they are identical to the parent egg cell.arrow_forwardWhich of the following mechanisms contributes to genetic variation through sexual reproduction via the random orientation of pairs of homologous chromosomes at metaphase of meiosis I?
