What would you expect a heterozygous roan bull to look like if the trait showed incomplete dominance instead? Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse. (6, 7) In many ways! Meiosis is the production of gametes for sexual reproduction. The four cells have the identical DNA sequences. Genetic Composition. Each daughter cell gets one complete set of chromosomes, i.e., one of each homologous pair of chromosomes. Sex cells, sperms in males, and eggs in females are a result of meiosis. In both cycles, the stages are common prophase, metaphase, anaphase and telophase. In mitosis, the nuclear membrane is broken down, spindle fibres . Answer: Option B Solution: Unlike Mitosis, Meiosis results in the formation of 4 Genetically different cells. Tags: Question 15 . Concept note-1: If False, change it.

Cells spend most of their time in this phase. Telophase is quickly followed by cytokinesis. In organisms that are diploid, the end result is cells that are haploid. The cell grows. Whenever an individual stops drinking, the BAL will ________________. This happens in metaphase of mitosis and metaphase II of meiosis. Mitosis and meiosis are both types of cell division. Mitosis is a continuous process of cell division which occurs in all types of living cells. mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells. Instead, these cells assemble membrane proteins (in vesicles that bud off the Golgi apparatus) in their interior at right angles to the spindle apparatus. Prophase I: During prophase of meiosis I, the chromosomes join in homologous pairs. The nucleoli and the nuclear membrane degrade. Open a web browser and go to the following site: This site will provide an interactive test of your ability to identify the stages of mitosis.
