Final answer:
A double tetrasomic cell has a chromosome content of 10n, where 2n is the number of chromosomes in a normal diploid cell. For a typical organism with diploid muscle cells having 32 chromosomes, the gametes would contain 16 chromosomes. Diploid cells have twice the number of chromosomes as haploid cells.
Step-by-step explanation:
The chromosome content of a double tetrasomic cell is 2n + 2 + 2. Since a normal diploid cell is designated as 2n, in a situation where a cell is double tetrasomic, it has two extra copies of two different chromosomes. For example, if the diploid number (2n) is 6, then the double tetrasomic number would be 6 + 2 + 2, which equals 10. Therefore, the answer is b. 10n.
In the case of a typical organism with muscle cells that have 32 chromosomes, the gametes would have half this number. Since muscle cells are diploid with 2n = 32, the gametes, being haploid, would contain 16 chromosomes (n = 16).A diploid cell has twice the number of chromosomes as a haploid cell. During meiosis, a diploid cell divides to produce four haploid daughter cells.
