Question

Cross between unrelated organisms is?

• A. Hybridisation
• B. Heterosis
• C. Test cross
• D. Back cross

Answer 1

The correct option is A Hybridisation

Hybridisation is an offspring of two animals or plants of different breeds, varieties, species or genera.

Heterosis is the increase in growth, size, fecundity, function, yield or other characters in hybrids over those of the parents

Test cross is a genetic cross between a homozygous recessive individual and a corresponding suspected heterozygote to determine the genotype of the latter.

Back cross is the cross (a hybrid) with one of its parents or an organism with the same genetic characteristics as one of the parents.

Thus, the correct answer is option A.
