Question
In backcross method of breeding, the hybrid
and the progenies in the subsequent generation are repeatedly backcrossed to one of the parents of the ………….Solution
A cross between a hybrid and one of its parents is known as backcross. In backcross method of breeding, the hybrid and the progenies in the subsequent generation are repeatedly backcrossed to one of the parents of the F1. As a result, the genotype of backcross progeny becomes increasingly similar to that of the parent to which the backcrosses are made.
The greatest number that will divide 398,436, and 542 leaving 7, 11, and 15 as remainders, respectively, is:

`1804/898-:99/699xx749/751=?`
215.003X4.021 + 11.05 + 71.02 =?
(462.23 × 127.84 ÷ 153.88) ÷ √(31.98 × 7.92) = ? ÷ 15.15
(400.01% of 149.89) ÷ 49.97 = ?2 ÷ (95.98 ÷ 31.99)
Two trains, 'P' and 'Q', are moving with speeds of 16 m/s and 24 m/s, respectively. The lengths of the trains are in the ratio 3:...
(168.24 ÷ 23.98) x 19.81 + ? = 176.33
( 1000)1/3 × 10.11 × 4.97 ÷ 10.32 =? – 15.022
75.01 + 344.923 - 179.93 = ?3 of (√678 + 3.89)
