- Q1Which diagram demonstrates how crossing-over contributes to genetic variety during meiosis?30sB.6.G: Meiosis
- Q2During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material —increases the genetic variationreduces the diploid number to the haploid numberreduces the probability of mutationsincreases the haploid number to the diploid number30sB.6.G: Meiosis
- Q3Human body cells each have 46 chromosomes in their nuclei. Meiosis is necessary in order to ensure that each gamete produced in the human body has —46 chromosomes92 chromosomes12 chromosomes23 chromosomes30sB.6.G: Meiosis
- Q4Sexual reproduction in animals depends on the production of gametes. Which of these processes produces gametes in animals?MeiosisBinary fissionMitosisFertilization30sB.6.G: Meiosis
- Q5Crossing-over between nonsister chromatids during meiosis is significant in heredity. This process most likely leads to an increase in which of the following?Number of gametesThe expression of dominant traitsThe occurrence of polyploidyGenetic variation30sB.6.G: Meiosis
- Q6In the early 1900s, Thomas Hunt Morgan was among the first scientists to contribute to the chromosome theory of heredity. Morgan's investigations into heredity in fruit flies led him to propose that the event represented in the diagram sometimes occurs. Which statement about the event represented in the diagram is valid?The event represents RNA translation in the smooth endoplasmic reticulum.The event produces genetically identical daughter cells.The event takes place in bacterial cells.The event provides genetic diversity in eukaryotic cells.60sB.6.G: Meiosis
