Detailed explanation-1: -Chromosome duplication occurs between meiosis I and meiosis II. the genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material (exogenous DNA) from its surroundings and taken up through the cell membrane(s).

Detailed explanation-2: -In meiosis, the chromosomes duplicate (during interphase) and homologous chromosomes exchange genetic information (chromosomal crossover) during the first division, called meiosis I. The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes.

Detailed explanation-3: -False. Meiosis is preceded by one round of DNA replication so that each chromosome is duplicated to consist of two identical sister chromatids joined at the centromere. During meiosis I, homologous chromosomes pair and separate into different daughter cells.

Detailed explanation-4: -Interkinesis lacks an S phase, so chromosomes are not duplicated. The two cells produced in meiosis I go through the events of meiosis II in synchrony. During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes.

Detailed explanation-5: -In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.
