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 actually a type of cell division that occurs in the testes of males and in the ovaries of females. Meiosis leads to the formation of cells bearing half the normal number of chromosomes. The process is also referred to as spermatogenesis in males and oogenesis in females. Meiosis does not occur in asexual organisms. It occurs only in organisms that reproduce sexually.All plants and animals undergo meiosis.
