normal grep would have searched only for lines with a literal +. fgrep. fgrep is an acronym that stands for Fixed-string Global Regular Expressions Print. fgrep (which is the same as grep -F) is fixed or fast grep and behaves as grep but does NOT recognize any regular expression meta-characters as being special.
. Meiosis results in the direct production of gametes. 2. A cell that has successfully completed meiosis has a chromosome number called Haploid. 3. If a species normally has 52 chromosomes, the cells it produces by Meiosis will each have 26 chromosomes.
Meiosis is a process by which we can halve the number of chromosomes. It takes place whenever the organism has to produce daughter cells that have half the number of chromosomes as the parent cells. In humans, meiosis occurs in spermatogonial and oogonial cells to produce sperms and eggs respectively. In higher plants which have a dominant diploid sphorophytic phase, the gametophytic phase is produced by meiosis. Meiosis occurs in almost all the higher living organisms.
