Summary Introduction
Introduction: Reproduction is an important phenomenon for ensuring the survival of species. The two different modes of reproduction are sexual reproduction and asexual reproduction. The asexual reproduction involves the production of offspring with genes inherited from a single parent. Whereas, the sexual reproduction involves the fusion of two haploid gametes to form a diploid zygote. One of the two gametes comes from male and the other gamete comes from female

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 correct
Spermatogoniaa. are haploid germ cells.b. are mature haploid cells.c. are male gametes.
d. have flagella.
e. are diploid germ cells.
Why is a second polar body expelled after fertilisation? a) To remove excess cytoplasm b) Because the oocyte must reactivate the incomplete meiosis before fusing with the sperm c) Before fusion with the sperm it must complete mitosis d) The fertilised oocyte is not a haploid cell until it expels the sperms mitochondria

- In a possible future scenario, male fertility drops to zero, but, luckily, scientists develop a way for women to pro-duce babies by virgin birth. Meiocytes are converted di-rectly (without undergoing meiosis) into zygotes, which implant in the usual way. What would be the short- andlong-term effects in such a society?arrow_forwardThe main function of the acrosome reaction is to (a) activate the egg (b) improve sperm motility (c) prevent interspecific fertilization (d) facilitate penetration of the egg coverings by the sperm (e) cause fusion of the sperm and egg pronucleiarrow_forwardIn females, meiosis is not completed (a) until birth.

- One day while walking across campus, you see a female butterfly laying fertilized eggs, as shown in the image: 1. What type of ovarioles would the adult female butterfly have (hint: remember the Order of butterflies)? a. Panoistic ovarioles b. Plasmatocytic ovarioles c. Polytrophic ovarioles d. Collaterial ovarioles e. Telotrophic ovarioles 2. Which combination of mechanisms would the butterfly use to supply vitellogenins/maternal mRNAs to the developing oocytes? a. Follicular epithelial cells/trophocytes contained within the follicle b. Apical cells of germarium/nutritive cords c. Follicular epithelial cells/nucleus of the oocyte d. Prefollicular tissue in germarium/trophoocytes that remain in germarium 3.
