Question

The superiority of the hybrid obtained by cross breeding is called as heterosis or hybrid vigour a. true b. false​

Answer 1

Answer:

Heterosis is the phenomenon in which the progeny have the superior characters when compared with the parents. It is also called as hybrid vigour. There may be an increase in characteristics such as size, growth rate, fertility and yield of a hybrid organism. Plant and animal breeders exploit heterosis by mating two different pure-bred lines that have certain desirable traits. The progeny which is produced may have the desirable characters from both the parents and thus, is more superior than the parent
