This set of Agricultural Biotechnology Multiple Choice Questions & Answers (MCQs) focuses on “Genetic Engineering Applications – Transgenic Plants”.
1. Phenotypic models are used to follow segregation of genes.
a) True
b) False
View Answer
Explanation: The most of the agronomic characters are not associated with scorable phenotypic characters. Discovery of restriction enzymes that cleave DNA have evolved the molecular marker technology.
2. DNA molecular markers cannot be present for certain genotypes.
a) True
b) False
View Answer
Explanation: The number may vary from hundreds to thousands. They are stable markers and are independent of plant growth stage and external environment.
3. What is the average number of species containing transgenic plants?
a) 20
b) 30
c) 40
d) 50
View Answer
Explanation: Up till 1980s, productions of transgenic plants were restricted mainly to tobacco, petunia or tomato of the family solanaceae. The production of transgenic plants has now been extended to several monocotyledons like wheat, maize, rice and oats.
