is a general condition when an organism gains or loses one or more chromosomes but not a complete set. 2. is a general condition where complete haploid sets of chromosomes are present. 3. is a loss of one chromosome from an otherwise diploid genome. 4. is a gain of one chromosome in addition to an otherwise diploid genome. 5. is a trisomy of chromosome 13 in humans. 6. is a trisomy of chromosome 18 in humans. 7. is the addition of one or more extra sets of chromosomes, identical to the normal haploid complement of the same species. 8. is the case of polyploidy when the chromosomes originate from the hybridization of two different species, usually closely related.

The correct term for each description s given below:

Explanation:

1. aneuploidy - is a general condition when an organism gains or loses one or more chromosomes but not a complete set.

2. Euploidy - is a general condition where complete haploid sets of chromosomes are present.

3. Monosomy- is a loss of one chromosome from an otherwise diploid genome.

4. Trisomy- is a gain of one chromosome in addition to an otherwise diploid genome.

5. Patau syndrome -is a trisomy of chromosome 13 in humans.

6. Edwards syndrome -is a trisomy of chromosome 18 in humans.

7. autopolyploidy -is the addition of one or more extra sets of chromosomes, identical to the normal haploid complement of the same species.

8. allopolyploidy - is the case of polyploidy when the chromosomes originate from the hybridization of two different species, usually closely related.
