Given below are two statements:
Statement I: A pureline variety is a variety which obtained from many heterozygaus plants of cross pollinated crop.
Statement II: A pureline become genetically variable with time due to mechanical mixture, natural hybridization and mutation.
In the light of the above Statements, choose the correct answer from the options given below:
Statement I is false because a pureline variety is not obtained from many heterozygous plants of cross-pollinated crops. A pureline is derived from a single homozygous individual through self-pollination over successive generations to maintain genetic uniformity. Statement II is true. While purelines aim to maintain genetic uniformity through strict self-pollination, over time, genetic variability may still occur due to factors such as mechanical mixture, natural hybridization, and mutation. These processes can introduce genetic variations in a pureline despite efforts to maintain purity through self-pollination.
(80.95) (1/4) + (3.05) 3 - 119.78 × 2.15 + (14.98)2 = ?
18.22 × 7.99 + 156.15 = ?
(98.03 + 186.98) ÷ 19.211 = 89.9 – 20.23% of ?
(1011 × 4.465 + 1012 × 0.3535) ÷ (160 × 10⁵) = 10? ÷ 2
...(899.117 + 1.1121) X 72.731 = ? + 49.95 X 64.78 + 29.50
24.99% of 1619.78 + (1259.84 ÷ 12.24) = ? × 16.98
124.88% of 1199.85 + 99.99 ÷ 3.99 = ?
(22.03 + 89.98) ÷ 14.211 = 89.9 – 25.23% of ?
(?)2 = (5.99)2 + (7.88)2 + 43.99
