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.
Genetic recombination happens in meiosis 1, specifically in prophase 1, when crossing over happens between the two inner chromatids of a synapsed pair of homologous chromosomes. 3. Replication of DNA happens BEFORE meiosis begins, so it doesn't happen in either meiosis 1 or meiosis 2. It happens during interphase.
