Question: Chromosome number of Ber cv. "Umran" is: (IGKV CET Horti 2021)
Options:
24
48
92
36
✅Explanation:Ber, also known as jujube (Ziziphus mauritiana Lamk.), is a fruit tree with several cultivated varieties. The chromosome number of a plant variety refers to the total number of chromosomes in each cell's nucleus.
-Umran: A specific cultivar of Ber known for its desirable characteristics.
-48 chromosomes: Research shows that Umran has a somatic chromosome number of 2n = 48, meaning each cell in Umran has 48 chromosomes, with 24 inherited from each parent. This classifies Umran as a hexaploid (six sets of chromosomes), more than the typical diploid (two sets).
