Two features present in meiosis but absent in mitosis are
Options
- APairing of non-homologous chromosomes
- BPairing of homologous chromosomes and recombination between them
- CReplication of chromosome
- DAll of these
Correct answer
B. Pairing of homologous chromosomes and recombination between them
Step-by-step solution
Homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci. One homologous chromosome is inherited from the organism's mother; the other is inherited from the organism's father. They have a tendency to pair with each other during meiosis and undergoes crossing over to produce new genetic recombinations.
