Which statement best explains the significance of meiosis?
Which statement best explains the significance of meiosis in the evolution of a species? Meiosis produces eggs and sperm that are alike. Meiosis provides for chromosomal variation in the gametes produced by an organism.
Which of the following statement best explains the role of meiosis in reproduction?
Which of the following statements best explains the role of meiosis in reproduction? Meiosis makes it possible for a zygote to have the correct number of chromosomes. A student wants to examine the cells produced as a result of meiosis under a microscope. … Meiosis produces cells in the haploid state.
What is the significance of meiosis explain?
Meiosis is responsible for the formation of sex cells or gametes that are responsible for sexual reproduction. It activates the genetic information for the development of sex cells and deactivates the sporophytic information. It maintains the constant number of chromosomes by halving the same.
Which statement best explains the significance of meiosis in helping to maintain the continuation of a species?
Which statement best explains the significance of meiosis in helping to maintain continuation of a species? Meiosis provides for chromosomal variation in the gametes produced by an organism.
Which statement best summarizes the importance of meiosis to reproduction quizlet?
Which statement best summarizes the importance of meiosis to reproduction? It produces gametes that are needed for sexual reproduction. According to the endosymbiotic theory, which cellular process was involved in the evolution of mitochondria and chloroplasts?
Which of the following statement best describe meiosis?
The statement that best describes meiosis is C. separation of sister chromatids.
What is the significance of meiosis and mitosis?
Mitosis and meiosis both involve cells dividing to make new cells. This makes them both vital processes for the existence of living things that reproduce sexually. Meiosis makes the cells needed for sexual reproduction to occur, and mitosis replicates non-sex cells needed for growth and development.
What is the significance of meiosis to the continuity of life?
Meiosis. The process of meiosis preserves genetic continuity for future offspring by ensuring that two sexually reproducing organisms produce offspring that have the same number of chromosomes as the parents.
What is the significance of meiosis in gametogenesis?
During the process of gametogenesis, a germ cell undergoes meiosis to produce haploid cells that directly develop into gametes. Hence, in animals, meiosis is an integral part of gametogenesis.
Which process normally occurs during meiosis but not during mitosis?
In meiosis , synapsis ( Pairing of homologous chromosome ) , Crossing over ( exchange of chromosomal segment between nos sister chromatids ) occurs which does not occur in mitosis.
What event in meiosis explains why gametes are haploid?
In meiosis I, homologous chromosomes are separated, which means that the cells produced by meiosis I are haploid. Haploid cells have ONE allele for each gene because every chromosome has a different set of genes (there are no homologous pairs).
Why are two phases of meiosis important for gamete formation?
Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!
