Answer :
The correct answer to the question is:
(4) Polyploidy
Explanation:
1. Polyploidy is a condition where an organism has more than two complete sets of chromosomes. This can occur naturally or be induced artificially.
2. In the context of the question, when a gamete (a sex cell) contains double the normal set of chromosomes (2n) or triple the normal set (3n), it is termed as polyploidy.
3. Translocation refers to the movement of a segment of chromosome to a non-homologous chromosome, not an increase in the number of chromosomes in a gamete.
4. A gene mutation involves alterations in the DNA sequence, not changes in the number of chromosomes.
5. Polydactyly is a genetic condition characterized by extra fingers or toes, and it is unrelated to the number of chromosomes in a gamete.
In summary, the condition described in the question where a gamete contains 2n or 3n chromosomes is known as polyploidy, indicating an abnormal number of chromosome sets.
