The fusion of non-reduced gametes will produce
a. somatic doubling
b. allopolyploid
c. autopolyploid
d. haploidy
e. Trisomies
Answer - The fusion of unreduced gametes will produce
b. Allopolyploid
Explanation = the fusion of unreduced gametes will produce allopolyploid.
Unreduced gametes are the gametes with somatic chromosome number.
Unreduced gametes are frequently involved in interspecific hybridization facilitating allopolyploidisation.
