Textbook Question
Chapter 39.1, Problem 1TYK
Choose the correct statement.
- The majority of animals reproduce by asexual reproduction.
- Budding, regeneration, and parthenogenesis account for reproduction in nearly all invertebrates.
- A zygote is the haploid organism produced by the union of a sperm and an egg.
- Potentially beneficial alleles are more likely to accumulate in species that reproduce sexually than in asexually reproducing species.
- In asexual reproduction, gametes from each parent join to form a zygote.

- Meiosis The process of meiosis Meiosis is a special type of cell division necessary for the production of sex cells (gametes) for the purpose of sexual reproduction. 2N cell (diploid). N is the haploid number of chromosomes. Each chromosome is replicated. DNA replication precedes meiosis. If genetic mistakes (mutations) occur here, they will be passed on (inherited by the offspring). Crossing over has occurred. Meiosis involves a single chromosomal duplication followed by two successive nuclear divisions, and it halves the diploid chromosome number. Homologous chromosomes pair up. The pairs are separated. An overview of meiosis is shown on the right. Meiosis occurs in the sex organs of plants and animals. An intermediate cell forms with a replicated copy of each chromosome. Meiosis produces variation During meiosis, a process called crossing over may occur when homologous chromosomes may exchange genes. This further adds to the variation in the gametes. Chromatid The chromosomes line…arrow_forwardMULTIPLE CHOICE: Select the BEST ANSWER for each item by ENCIRCLING THE LETTER corresponding to the best choice. Which of the following statements is INCORRECT? The halving of chromosome number during gamete formation, followed by the union of two gametes at fertilization, allows a constant 2n number of chromosomes to be maintained from generation to generation in all individuals of a species. Meiosis ensures that all somatic cells of the developing individual have identical diploid chromosome sets. The number of chromosomes in a normal diploid cell is 2n. Gametes and other cells that carry only a single set of chromosomes are called haploid. Which of the following statements is INCORRECT? Scientists usually analyze the chromosomal makeup of a cell during metaphase because this is when the chromosomes are most visible. During metaphase, individual chromosomes have duplicated and condensed from thin threads into compact rod-like structures. Each chromosome, during metaphase,…arrow_forwardIn C. elegans there are two sexes: hermaphrodite and male. Sex is determined by the ratio of X chromosomes to haploid sets of autosomes (X/A). An X/A ratio of 1.0 produces a hermaphrodite (XX), and an X/A ratio of 0.5 results in a male (XO). In the 1970s, Jonathan Hodgkin and Sydney Brenner carried out genetic screens to identify mutations in three genes that result in either XX males (tra-1, tra-2) or XO hermaphrodites (her-1). Double-mutant strains were constructed to assess for epistatic interactions between the genes (see table). Propose a genetic model of how the her and tra genes control sex determination.arrow_forward
