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.
1 In male animals (also in man) meiosis occurs in the testis. A sperm mothercell produces four sperm cells.  In female animals (also in woman) meiosis occurs in the ovaria. During the meiotic process asymmetrical divisions occur so that all cytoplasm is gathered in only one of the meiotic products . This large cell becomes an egg cell, whereas the other cells produced by meiosis disappear.
