Combination Monosomic Halpoid Nulisomic Trisomic 21 28 42 43
B)
Combination Monosomic Halpoid Nulisomic Trisomic 7 28 4 43
C)
Combination Monosomic Halpoid Nulisomic Trisomic 21 7 42 43
D)
Combination Monosomic Halpoid Nulisomic Trisomic 41 21 40 43
Correct Answer: D
Solution :
The basic chromosome number of wheat is 7 (x=7) and its hexaploid species contains 42(6x7) chromosomes. Thus, its monosomic (one chromosome missing) contains 41 (42?1) chromosomes. Haploid contain 21 (half to the 42) chromosomes. Nullisomic (one chromosome pair missing) contains 40 (42?2) chromosomes and trisomic contain (one chromosome extra) 43 (42+1) chromosomes.
