A karyotype refers to a full set of chromosomes from an individual that can be compared to a normal karyotype for the species via genetic testing. A chromosome anomaly may be detected or confirmed in this manner. Chromosome anomalies usually occur when there is an error in cell division following meiosis or mitosis.
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.
