Answer :

I) Independent assortment.

II) Nucleosomes, DNA, chromatin, chromosomes.

III) 3.

EXPLANATION:

Recombination scrambles pieces of maternal and paternal genes, which ensures that genes assort independently from one another.

➻ We know that Chromatin is a complex of DNA and proteins that forms chromosomes. Chromatin looks like beads on a string. The beads are called nucleosomes. Each nucleosome is composed of DNA.

Triploids with three different alleles can easily be detected because they have a unique phenotype.

The process involved in genetic recombination is INDEPENDENT ASSORTMENT. The correct order from smallest to largest is DNA, nucleosomes, chromatin, chromosomes. In a triploid organism, there are 3 ALLELES for each gene.

In independent assortment, different gene variants or 'alleles' are independently and randomly assorted into daughter cells, which allows genetic recombination.

In eukaryotic organisms, DNA is associated with histone proteins in order to form nucleosomes, which arrange in higher organization structures called chromatin fibers.

Subsequently, chromatin fibers condense to form structures called chromosomes.

A triploid organism (3n) contains three sets of homo-logous chromosomes, each one containing one allele for a given locus.

In conclusion, the process involved in genetic recombination is INDEPENDENT ASSORTMENT. The correct order from smallest to largest is DNA, nucleosomes, chromatin, chromosomes. In a triploid organism, there are 3 ALLELES for each gene per cell.
