Summary Introduction
Introduction:
Reproduction is a biological process of the formation of offspring for their parents. It is a fundamental feature of life. The reproduction occurs in two forms, asexual reproduction and sexual reproduction. The asexual reproduction includes binary fission, budding, parthenogenesis and so on.

Which of the following correctly describes hermaphroditism?
A.
It is an example of sexual reproduction because it involves a male and a female.
B.
It is an example of asexual reproduction because only one individual needs to be involved.
C.
It is an example of sexual reproduction because it involves fusion of two gametes.
D.
It is an example of asexual reproduction because the offspring are genetically identical to the parent.

C.
Spermatogenesis and oogenesis are both examples of asymmetric cell division.
D.
Spermatogenesis involves only symmetric cell division whereas oogenesis involves asymmetric cell division.

Select one:
A. two eggs are fertilized by two sperm cells, resulting in a fraternal twin.
B. High levels of FSH stimulate the maturation of three ovums.
C. Two eggs are fertilized by one sperm cell, resulting in a monozygotic twin.

- What is the relationship between a primary spermatocyteand a spermatogonium?a. They are genetically identical.b. The spermatocyte is haploid and the spermatogonium is diploid.c. The spermatocyte has a flagellum; the spermatogonium does not.d. Both b and c are correctarrow_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 description below explains how the hormones released in birth control pills causes natural ovulation to cease? Select one: a. Birth control pills release estrogen. Estrogen controls the secondary sex characteristics of the female body. b. Birth control pills release progesterone. Progesterone feeds back to the pituitary gland, thereby inhibiting FSH and LH and in effect, stopping the ovarian and menstrual cycle. c. Birth control pills release progesterone. Progesterone causes an increase in FSH, thereby increasing the production of follicles. d. Birth control pills release estrogen. Estrogen feeds back to the posterior pituitary, causing an increase of LH and thereby ceasing the ovarian cycle.arrow_forward

It occurs only in germline cells of the reproductive organsarrow_forwardWhich of the following is a major difference between spermatogenesis and oogenesis? a. Spermatogenesis involves meiosis, and oogenesis involves mitosis. b. Spermatogenesis is continuous, but oogenesis is variable. c.

- 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_forwardIs this true or false? a. Fertilization is followed by a cleavage, a period of rapid cell division without growth. b. From the process above, this results in the production of a large number of cells called blastomeres. c.
