16.) Occurs in prokaryotes. 17.) Occurs in eukaryotes. 1. Describe how meiosis and sexual reproduction create genetic diversity. 2. Sketch a homologous pair of chromosomes and include the alleles for three different genes. 4. Explain the impact of crossing over on the inheritance of alleles. ...
One major difference between mitosis and meiosis that can contribute significantly to genetic diversity in offspring is referred to as "crossing over" or "chromosomal crossover." Crossing over occurs only in meiosis. Homologous chromosomes can physically "swap" chromosomal segments, thereby ensuring that...
百度试题 结果1 题目During which process does crossing over occur? A. Mitosis B. Meiosis I C. Meiosis II D. Both mitosis and meiosis 相关知识点: 试题来源: 解析 B。原因:交叉互换发生在减数第一次分裂过程中,同源染色体配对时。反馈 收藏 ...
Meiosis introduces genetic diversity through crossing over and independent assortment, leading to gametes that are genetically distinct from each other and from the parent cells. 12 Can mitosis occur in all types of cells? Mitosis occurs in somatic cells, which are all cells of the body except fo...
In this lesson, learn about the process of meiosis, what is produced by the process of meiosis, genetic recombination in meiosis, and crossing over...
Prophase I (Meiosis) homologous chromosomes pair up and form tetrads, crossing over occurs Synaptonemal complex A zipper-like protein structure that causes replicated homologs to become physically connected during prophase of meiosis I; sets the stage for crossing over. Tetrad 2 homologous chromosomes ...
Cytokinesis - meiosis then occurs and produces four haploid cells, each of which contains a single copy of every chromosome. Non-disjunction Non-disjunction increasing diversity mechanism 1. Chromosomes are randomly segregated to gametes, which results in new assortments of maternal and paternal chromos...
Which stage of meiosis is most similar to mitosis? Why? What are the various stages of mitosis? List and describe the steps of mitosis. Describe what occurs in each of the stages of mitosis? In which of the following processes does crossing over occur? a. mitosis b. meiosis c. both mit...
During meiosis, crossing over occurs between View Solution The events shown below occur during different phases - A. Centromere splits, chromatids separate and move to opposite poles, chromatids are now called chromosome B. Chromosomes cluster at opposite poles, decondensation of chromosome, reappeara...
In the process of meiosis, how many viable eggs are produced by the female each time meiotic cell division occurs? What is the function of cell division? What is the role of DNA and RNA in mitosis? Describe the events that occur during interphase. ...
