[#536] A variety is eligible for protection when it confirms the
Correct Answer

(D) All of the above

Explanation

Solution: A variety is eligible for protection when it confirms Novelty, Distinctness, Uniformity and stability. Plant variety protection provides legal protection of a plant variety to a breeder in the form of Plant Breeder's Rights (PBRs). PBRs are intellectual property rights that provide exclusive rights to a breeder of the registered variety. The temperature fluctuation at any one point is called stability, and the largest temperature difference between any two points in the bath is called uniformity. The temperature at any point varies regularly between two limits but occasionally a larger variation is observed.

[#537] Synthesis of a gene in a test tube and its transfer to a cell is called
Correct Answer

(A) Genetic engineering

Explanation

Solution: The synthesis of a gene in a test tube and its transfer to a cell is called Genetic engineering. Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism. This may involve changing a single base pair (A-T or C-G), deleting a region of DNA, or adding a new segment of DNA.

[#538] The individual having both the alleles of similar character is said to be
Correct Answer

(B) Homozygous

Explanation

Solution: The individual having both alleles of similar character is said to be Homozygous. Zygosity is the degree to which both copies of a chromosome or gene have the same genetic sequence. If both alleles of a diploid organism are the same, the organism is homozygous at that locus.

[#539] A homogeneous population includes
Correct Answer

(D) None of these

Explanation

Solution: A homogeneous population does not include An inbred line, A pure line, or the Progeny of a clone. An inbred line is a population in which closely related animals, such as siblings or parents and offspring, have been repeatedly mated so that nearly all genetic variation is lost. A pure line is the progeny of a single self-fertilized homozygous plant. The progeny of a clone is genetically and physically identical to the parent.

[#540] Seed moisture varies from crop to crop and ranges from
Correct Answer

(D) 9 - 12%

Explanation

Solution: Seed moisture varies from crop to crop and ranges from 9 - 12%. The moisture content is the amount of water in the seed and is usually expressed as a percentage. It can be expressed on either a wet-weight basis or a dry-weight basis.
