Answer:

Gene flow or allele flow is the transfer of genes or genetic variation among populations.

This gene flow or migration of genes help maintain the similarities between the species or genetic diversity in a population but slows the process of speciation and variation in the population.

The causes of gene flow are:

1. Random mating- random mating among organisms of different population causes movement of alleles in populations.

3. Recombination of chromosomes during meiosis- can change the alleles of the organism.

2. Mutation- mutation in DNA can create new alleles in a population.

4. Random fertilization.

Answer:

The correct answer will be-pachytene, prophase I,

Explanation:

Tetrad is the structure formed during the meiotic type of cell division which produces four daughter cells.

The tetrad structure is seen under the microscope during the pachytene substage of prophase I.

The tetrad structure is formed when four sister chromatids are aligned together in a cell before the crossing over event or recombination has to take place. The tetrad formation allows the crossing over to take place in pachytene.

Thus, pachytene, prophase I is the correct answer.
