A certain species of plant has 2n = 16 chromosomes. How many chromosomes per cell would you expect to find in a somatic cell of an individual with each of the following changes? Monosomy Monoploid Nucleonic Triploid Trisomy Tetraploid Why are autopolyploid usually sterile, while allopolyploids are usually fertile? As part of your answer, explain what the difference is between these two types of polyploidy.

Solution

2n=16

Monosomic: 15 (2n-1)
Monoploid: 8 (n)
Nullisomic: 14 (2n-2)
Triploid: 24 (3n)
Trisomic: 17 (2n+1)
Tetraploid: 32 (4n)
