The main events in meiosis During the first division, chromosomes pair and sections of are exchanged between non-sister chromati
ds as a result of crossing over (prophase I). The nuclear membrane fragments and pairs of homologous chromosomes become aligned on the . One chromosome of each pair is lined up on either side of the equator (metaphase I). The pairs of chromosomes are separated and pulled apart (anaphase I) to either pole to form the first two daughter nuclei (telophase I). divides the cytoplasm and each daughter cell now contains the number of chromosomes.During the second division, the nuclear membrane fragments and individual chromosomes composed of 2 sister become aligned on the equator of the spindle (metaphase II). The pairs of chromatids are separated and pulled apart (anaphase II) to either to form daughter nuclei as the nuclear membranes reform around the new nuclei (telophase II). Cytokinesis divides the two cells into fou
Cytokinesis divides the two cells into four daughter cells.
Explanation:
Meiosis is a type of cell division in which a single cell is divided into four daughter cells. These daughter cells are haploid i. e. half number of chromosomes. This type of cell division occurs only in sex cells of male and female organisms. There are two phases of meiosis. In meiosis 1, a single cell is divided into two daughter cells while in meiosis 2, these two daughter cells again divided into four daughter cells.
The advantage of natural breeding are the following: 1. cattle produce may eradicated hereditary sickness. 2. the cattle that is produce is fitter, stronger and can survive through harsh condition because they are use to it. 3. they can produce better food
Null hypothesis have a tendancy of never raise to that status. Yet, if a hypothesis is tested and prooven to aply having an universal vocation of being aplyed thrn it could become a Postulate
antibiotic resistant is a consequence of evolution via natural selection. the antibiotic action is an environmental pressure;those bacteria which have a mutation allowing them to survive will live on to reproduce
