Hisardale Sheep Breed Origin Explained
The Hisardale sheep is a notable breed recognized for its specific genetic makeup, developed through strategic crossbreeding. Understanding the parentage of livestock breeds is crucial for animal husbandry and improving desirable traits like wool quality and meat production.
Crossbreeding for Hisardale Sheep
The Hisardale sheep breed was developed by crossing two distinct breeds: the Bikaneri sheep and the Marino sheep. This cross aimed to combine the hardiness and local adaptation of the Bikaneri breed with the superior wool quality of the Marino breed.
- The Bikaneri sheep, known for their adaptability to arid conditions, contribute resilience.
- The Marino sheep are globally acclaimed for their fine, high-quality wool.
Specifically, the cross involved using Bikaneri ewes (female sheep) and Marino rams (male sheep).
| Parent Breed Component | Breed Type |
|---|---|
| Ewes | Bikaneri |
| Rams | Marino |
This specific combination resulted in the Hisardale breed, which typically exhibits improved wool characteristics inherited from the Marino parent while retaining good adaptability from the Bikaneri parent.
Important Questions from Breeding
Which of the following is an indigenous dairy breed of cattle?
Given below are a few statements on use of plant breeding to develop improved varieties of a crop plant:
A: Genotypic/phenotypic variation in the desired trait should be available in the germplasm resources of the crop plant.
B: Availability of molecular markers linked to the trait of interest would decelerate the process of trait introgression into desired varieties.
C: Breeding procedures to improve plant varieties are generally more successful among sexually compatible species as compared to sexually incompatible species.
D: Co-dominant molecular markers cannot be used for selection of plants with the desired trait.
Which of the above statement(s) is/are INCORRECT?
Given below are some terms in column A and their corresponding properties/related terms in column B
Which one of the following options represents the most appropriate match between all terms of column A and B?Column X Column X A Bulk segregant
analysis(i) QTL analysis of wider genetic diversity using fewer individuals B NILS (ii) Mapping monogenic qualitative trails C Association mapping (iii) Co-dominant markers D SNPs (iv) Repeated backcrossing of F1 to recurrent parent Which one of the following approaches/markers would be typically used for discovering polymorphism between two closely related accessions of a crop plant?
A group of researchers are testing two new agents, M1 and M2 for their efficacy in selecting transgenic plants. When they performed tissue culture experiments using three explants, A, B, and C without Agrobacterium transformation, and selected the regenerated plants on M1 and M2, the following regeneration frequencies were obtained.
Regeneration frequencies (%) in presence of different concentration of agents Explant type M1 conc. (mg/L) M2 conc. (mg/L) 20 60 100 10 15 20 A 44% 21% Nil 8% Nil Nil B 53% 30% 10% Nil Nil Nil C 71% 42% 18% 15% 9% 4% Based on the above data, which one of the following conclusions is INCORRECT?
