Concept explainers
Would a pair of haploid offspring produced by parthenogenesis be genetically identical? Explain.
To explain: Whether the haploid offspring produced by parthenogenesis would be identical.
Concept introduction: Parthenogenesis is a unique kind of asexual reproduction. It involves the production of gametes, but the offspring are generated without the fertilization. This kind of asexual reproduction occurs in certain invertebrates such as bees, wasps, and ants.
Answer to Problem 46.1CR
Explanation of Solution
Haploid gametes are produced by meiosis cell division. Meiosis involves the random assortment of chromosomes and genetic recombination that brings variation in the genetic makeup of the gametes. So, the offspring produced will not be identical.

- If gametes had the same number of chromosomes as body cells, and an organism had 24 chromosomes in its body cells, how many chromosomes would it have after three generations? How does this illustrate the necessity of meiosis for gamete formation?arrow_forwardYou are observing fertilization in the lab and notice that a gamete underwent meiotic non-disjunction. Explain two possible outcomes for the zygote that will arise from this gamete?arrow_forwardMale honeybees, which are haploid, produce sperm by meiosis.Explain what unusual event (compared with other animals) mustoccur during spermatogenesis in honeybees to produce sperm.Does this unusual event occur during meiosis I or meiosis II?arrow_forward
- In humans, gametogenesis in both sexes relies on meiosis. However, spermatogenesis produces four gametes while oogenesis produces only one. Explain why this is so, including the specific structures or processes involved.arrow_forwardIf cell division during gametogenesis were non meiotic, what would be its consequences to future generations of diploid organisms?arrow_forwardEach sperm of a pea plant contain seven chromosomes. What are the haploid and diploids for this species?arrow_forward
- What is the probability for a spermatozoid to receive only maternal chromosomes (that were given by the mother of this man) ?arrow_forwardMitosis and meiosis are both important processes of cell division in the life cycle of a sexual organism.Discuss why both processes are necessary?arrow_forwardWhy is it risky for a haploid sperm cell to go through diffrencition after meiosis?arrow_forward

For each of the gametes produced by this cell, give thechromosome number of the zygote that would result if the gamete fusedwith a normal haploid gamete.arrow_forwardBy what mode of cell division would you expect sperm cells to be formed in the haploid male be?
