A.
2n = 48
B.
2n = 42
C.
2n = 24
Answer
D.
2n = 14

Answer: Option C

Solution

Answer: Option C
Solution:
The chromosome number of tomatoes is 2n = 24.
It is a diploid species with a haploid set of 12 chromosomes and a small genome. It is more than 75% of which is heterochromatin and largely devoid of genes. Most genes are found in long contiguous stretches of gene-dense euchromatin located on the distal portions of each chromosome arm.
