Correct Answer:- Option-B

Question34:-The ectopic expression of some transcription factors can increase the
efficiency of somatic embryogenesis (SE) induction and lead to the formation of

a transcription factor?

A:-LEC

B:-BBM

C:-NOR

D:-AGL 15

Correct Answer:- Option-C

D:-1971 with 7 structures
Correct Answer:- Option-D

Question36:-Osteogenesis imperfecta (Ol) is a human bone disease. The majority of
people with this disease have a dominant mutation in one of the two genes that
produce type 1 collagen, COL1A1 or COL1A2. However, this disease doesn't affect
everyone who has COLIA1 and COLIA2 mutations in the same way. In fact, some
people can carry the mutation but have no symptoms. Which of the following terms
explains the above phenomenon?

A:-Variable Expressivity
B:-Incomplete penetrance
C:-Codominance

D:-None of the above
Correct Answer:- Option-B
