Inferences are steps in reasoning, moving from premises to conclusions. Charles Sanders Peirce divided inference into three kinds: deduction, induction, and abduction. Deduction is inference deriving logical conclusions from premises known or assumed to be true, with the laws of valid inference being studied in logic.
Meiosis is the process by which most eukaryotic organisms, those with cells having an organized nucleus, produces sex cells, the male and female gametes. Cells normally have two copies of each chromosome, one donated from each parent.
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.
