1. Both are GM crops.
2. Both contain introduced foreign genes.
3. Both are worms.
4. Both have been the first ones in 'Human Genome Project', whose genes have been fully sequenced.

Q. Arrange the following in correct sequence with reference to sexual reproduction in Rhizopus
I. Formation of germ tube.
II. Formation of zygophores.
III. Formation of warty wall layer of zygospore.
IV. Secretion of trisporic acid.
The correct sequence is

1. IV, III, II, I
2. IV, II, III, I
3. II, I, IV, III
4. I, III, II, IV

Q. Choose the correct answers from the alternatives given.
Zygospores are not generally formed in cultures of Rhizopus developed from a single spore due to:
