Identify the term in the following that refers to "the group of individuals within a family of a species"
Show Hint
In forest progeny trials, half-sib and full-sib families are commonly evaluated to estimate heritability and breeding value.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Tree breeding and population genetics require precise hierarchical definitions to categorize genetic groups within a species.
Step 2: Detailed Explation:
Let us evaluate the given options:
- Sibling: In genetics, siblings are individuals that share one (half-siblings) or both (full-siblings) parents.
A family in tree breeding is defined as a group of offspring derived from a single cross or open-pollited mother.
Hence, a group of individuals belonging to the same family within a species are genetically referred to as siblings.
- Race: A race is a sub-population within a species that exhibits distinct, inherited phenotypic or physiological traits, usually associated with geographic or ecological isolation (provence).
This is a much broader category than a single family.
- Clone: A clone is a group of genetically identical individuals vegetatively derived from a single parent.
- Population: A population is a group of interbreeding individuals of the same species occupying a specific area, regardless of family boundaries.
Thus, siblings precisely represent the group of individuals within a specific family.
Step 3: Fil Answer:
The term referring to a group of individuals within a family of a species is sibling.
Hence, the correct option is (D).

Statement (I): Anogeissus latifolia is worked only as a component species of mixed forests as coppice-with-standards.
Statement (II): Terminalia arjuna tree is not a regular component of forest stand and is usually worked under selection and coppice with standards.
Choose the correct answer from the options given below: - The most important single factor affecting natural regeneration of Shorea robusta is the time lag between the falling of seed and the commencement of the ________.
- Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
Statement (II): Selection system is adopted for areas which are badly eroded and where regeneration is problem and regeneration is obtained by natural means, which may be supplemented by planting.
Statement (III): In coppice with standards system, a few standards are retained and the other trees above the exploitable diameter are clear felled and regeneration is obtained by means of coppice.
