In which of the following processes does crossing over occur? a. mitosis b. meiosis c. both mitosis and meiosis d. neither mitosis nor meiosis Crossing Over: Crossing over is the process where chromatids from different chromosom...
Which processes occur during meiosis and involve the movement of DNA from one homologous chromosome to another? Describe the objective of meiosis. What mechanism(s) in meiosis allow this to occur? What are the two mechanisms of variation in Meiosis, and during which stage...
This process is known to regulate intra-membrane proteolysis (Rip)[48], and typically produces proteins which are transcriptionally active and participate in the control of various cellular processes[6]. S2P action is not directly affected by cellular oxysterol levels, since this enzyme cannot act ...
Gametes (sperm and eggs) are created by meiosis, which creates four cells, each of which contains half the number of chromosomes as the original. During cell division, duplicated chromosomes line up down the center of the cell, and are then pulled apart to opposite poles of the cell. There...
Through recombination due to crossing over during meiosis I, new combinations of genes are created, thus recombination is responsible for creating new hereditary combinations, which cannot be found in previous generations. Answer and Explanation:1 ...
Which processes occur during meiosis and involve the movement of DNA from one homologous chromosome to another? Homologous chromosomes undergo crossing over during ___ of meiosis. In which phase does synapsis occur? a. anaphase I b. prophase I c. interkinesis d. telophase (a) ...
What are the sources of genetic variation during meiosis? What chromosome has the genetic mutation for diabetes? In which types of cell would mitosis occur? What is a chromosome? Which three processes are methods of genetic recombination? Sex-linked traits are carried on what chromosome? What gen...
New Genetic Combinations: New genetic combinations can come about during various events that occur in the meiotic division. Therefore it will result in gametes containing new combinations of genetic material. Answer and Explanation:1 Random ferti...
Which three processes are methods of genetic recombination? What is human genetic engineering? How is genetic engineering like computer programming? Crossing-over does not occur between any pair of homologous chromosomes during meiosis in male Drosophila. From what you have learned about meiosi...
