During meiosis, genetic recombination may occur more than once through the process of resulting in an increase in genetic variability.

Crossing-over

Explanation:

Crossing-over is a phenomenon that occurs in the Prophase stage of meiosis I. Two chromosomes of a homologous pair comes together in a process called SYNAPSIS to form a TETRAD structure. While the chromosomes synapses, breaks occur at corresponding points in the non-sister chromatids i.e in one chromatid of each chromosome. Since the chromosomes are homologous, breaks at specific points mean that the segments that are broken off contain specific genes i.e. alleles. The broken sections are then exchanged between the chromosomes to form complete new units, and each new recombined chromosome of the pair can go to a different daughter sex cell.

In meiosis, the maternal and paternal chromosomes can be shuffled into daughter cells in many different combinations. The resulting chromosomes are not entirely maternal, neither are they entirely paternal. This ensures genetic variation in sexually reproducing organisms.

lunar landing mission. apollo 11 was the first manned mission to land on the moon. the first steps by humans on another planetary body were taken by neil armstrong and buzz aldrin on july 20, 1969. the astronauts also returned to earth the first samples from another planetary body.
