Genetics and Animal Biotechnology
Assignment Code: MZO-002/TMA/2025
Maximum Marks: 100
Note: Attempt all questions. The marks for each question are indicated against it.
1. How did Mendel’s use of controlled crossbreeding in pea plants lead to the
discovery of dominant and recessive traits? Describe the Mendel’s laws of
heredity.
2. What is epistasis, and how does it affect the expression of traits? Provide
examples to describe the different types of epistasis, such as dominant
epistasis and recessive epistasis.
3. What are the different types of mutations and how do they affect the genetic
code and protein synthesis?
4. How do transcription factors and enhancers regulate gene expression in
eukaryotic cells, and what role do epigenetic modifications such as DNA
methylation and histone modification play in this process?
5. Compare the X-Y sex determination system with the Z-W sex determination
system, providing suitable examples.
6. Describe the key cytogenetic techniques of karyotyping and fluorescence in
situ hybridization (FISH) used to identify chromosomal abnormalities.
7. What are cloning vectors? How are they used in recombinant DNA
technology to insert foreign genes into host cells? Discuss the different
types of cloning vectors and their features.

8. Compare the processes of constructing a genomic library and a cDNA
library. Which type of library is used for studying gene expression?
9. What are transgenic animals? What are the key techniques used in the
creation of transgenic animals, and how do these methods contribute to
advancements in fields such as medicine and agriculture?
