Study Notes
Paper V- INTRODUCTORY ANIMAL BREEDING & GENETICS
- All questions in the examination are compulsory.
- Hindi medium students must respond in English, while English medium students must also answer in English.
Key Definitions and Concepts
- Father of Genetics: Gregor Johan Mendel (1822) established foundational principles of heredity.
- Middle Variance: Not specified; related to genetic variation within populations.
- H-bonds: Form between adenine and thymine in DNA molecules.
- Dominant Epistasis: The dominant epistatic ratio in F₁ generation varies based on genetic interactions.
- Longest Phase of Nuclear Division: Not specified; typically refers to the prophase stage.
- Spermatogenesis: Process by which sperm cells are formed in the testes.
- Hemophilia: A genetic disorder caused by a recessive gene located on the X chromosome.
- Inbreeding: Leads to an increased frequency of deleterious genes within a population.
- Jertrar Cattle: A crossbred variety derived from specific cattle breeds.
- Hybridization: The process of crossing two different species or breeds.
Key Terms to Define
- Heterosis: Phenomenon where hybrid offspring exhibit superior traits compared to their parents.
- Line Breeding: A form of selective breeding aimed at maintaining desired traits by mating individuals within a defined lineage.
- Sex Limited Gene: Genes that are expressed only in one sex, influenced by sexual characteristics.
- Transversion: A specific type of mutation where a purine is replaced with a pyrimidine or vice versa.
- Artificial Selection: Human-directed breeding process to enhance desired traits in organisms.
Additional Terms
- Crossbreeding: The process of mating individuals from different breeds or species for desired characteristics.
- Heredity: The transmission of genetic traits from parents to offspring.
- Median: A statistical measure that represents the middle value in a dataset.
- Epistasis: Interaction between genes where the presence of one gene masks or modifies the effect of another gene.
- Genotype: The genetic constitution of an individual, representing the alleles present for a specific trait.
