Which of the following conditions is the result of an autopolyploidy event where an organism possesses more than two complete sets of chromosomes derived from a single species?

A triploid 3n plant resulting from the fusion of a diploid 2n gamete and a haploid n gamete.

A human cell exhibiting trisomy 21, resulting in a total of 47 chromosomes.

A monosomic cell having only one copy of a specific chromosome in a diploid set.

A hybrid offspring produced by the mating of a horse and a donkey.

Which of the following describes the difference in gamete outcomes between nondisjunction in Meiosis I and nondisjunction in Meiosis II?

Meiosis I nondisjunction results in all four gametes being aneuploid, while Meiosis II nondisjunction results in 50% aneuploid and 50% normal haploid gametes.

Meiosis I nondisjunction leads to polyploidy, whereas Meiosis II nondisjunction leads to aneuploidy.

Meiosis I nondisjunction results in only n+1 gametes, whereas Meiosis II results in only n-1 gametes.

Meiosis I nondisjunction affects only autosomes, while Meiosis II nondisjunction affects only sex chromosomes.
