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 form of cell division that creates new combinations of genetic material in the newly-formed daughter cells. During this division, only half of the number of parent chromosomes are used, and meiosis takes place in four vital processes. Prophase is the first step in meiosis and occurs when the chromosomes condense to where they become visible inside the nucleus. Metaphase happens when microtubules come out of each spindle and attach to the kinetochore.
