Weekly Quiz Competition

Question 1
1 / -0

ICBN is connected with

A
Correct nomenclature of animals.

B
Correct nomenclature of plants.

C
Correct nomenclature of biochemicals.

D
All of the above.

Solution

The International Code of Botanical Nomenclature (ICBN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants. Its intent is that each taxonomic group of plants has only one correct name that is accepted worldwide. The value of a scientific name is that it is an identifier; it is not necessarily of descriptive value, or even accurate.
So, the correct option is 'Correct nomenclature of plants'.
Question 2
1 / -0

Related species which are reproductively isolated but morphologically similar are called

A
Allopatric

B
Sympatric

C
Sibling

D
Morphospecies

Solution

1. Allopatric species are those that have evolved in the course of time due to geographical separation between the two populations of the same species.
2. Sympatric species are those that have evolved from the ancestors that are existing in the same geographical area for a long period of time. There is no reproductive isolation of species observed in sympatric speciation.
3. Sibling species are morphologically similar, sometimes even indistinguishable by appearance, but nevertheless are reproductively isolated from one another leading to interesterify.
4. Morphospecies are groups of individuals that are morphologically similar and clearly distinguishable from individuals of other groups.
So, the correct option is 'Sibling'.
Question 3
1 / -0

Neontological species is

A
Species belonging to particular area

B
Species of a particular time

C
Living species

D
Both A and B

Solution

Neontological species are those species which are present in the living world. It is in contrast to paleontological species which includes the study of species that existed years ago.
So, the correct option is 'Living species'.
Question 4
1 / -0

The lowest category in taxonomic hierarchy is

A
Phylum

B
Subspecies

C
Species

D
Variety
Solution
- Species is a group of actually or potentially inbreeding population reproductively isolated from other such groups.
- It is the lowest taxonomic characteristics.
- Kingdom → Phylum → Class → Order → Family → Genus → Species
- It consists of individuals which have fundamental similarities and can be distinguished from other closely related species due to distinct morphological characters.
So, the correct option is 'Species'.
Question 5
1 / -0

Species belonging to different time periods are

A
Allochronic species

B
Parapatric species

C
Synchronic species

D
Allopatric species

Solution

1. Allochronic species: Those species that do not occur in the same geological period.
2. Parapatric species: The species evolved in geographically adjacent populations due to evolution.
3. Synchronic species: Those species that occur in the same geological period.
4. Allopatric species: The species formed by the geographic isolation of two or more populations.
So, the correct option is 'Allochronic species'.
Question 6
1 / -0

All the species of a genus possess same

A
Ancestry

B
Karyotype

C
Anatomy

D
Genetics
Solution
- A species is a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus.
- Hence All the species of a genus possess the same ancestry. This is the the reason for their close similarities. For example, genus equals has many species like Cabelas for the horse; vulgaris the ass zebra.
- So, the correct answer is 'Ancestry'.
Question 7
1 / -0

Biospecies is based on

A
Cytological traits

B
Reproductive isolation

C
Genetic isolation

D
Both B and C

Solution

The most accepted definition of biological species (Biospecies) was given by Ernst Mayr. He defined the species in terms of interbreeding. According to him, the species includes various groups of freely interbreeding natural populations isolated reproductively from such other groups. This leads to genetic isolation and thus speciation.
So, the correct option is 'Both B and C'.
Question 8
1 / -0

Species having many subspecies are

A
Monotypic/Microspecies

B
Allopatric

C
Sibling

D
Polytypic/Macrospecies

Solution

1. Monotypic species are those containing only one type of sub-species.
2. Allopatric species are those that have evolved in the course of time due to geographical separation between the two populations of the same species.
3. Sibling species are morphologically similar, sometimes even indistinguishable by appearance, but are reproductively isolated from one another leading to interesterify.
4. Polytypic species are those containing more than one sub-species.
So, the correct option is 'Polytypic/macro species'.
Question 9
1 / -0

ICBN was adopted in:

A
1951

B
1971

C
1961

D
1981

Solution

ICBN (International Code of Botanical Nomenclature) was adopted in the year 1961. It is the set of rules and recommendations dealing with the classification and botanical names that are given to plants. The nomenclature is universal and according to the system of binomial nomenclature.
So, the correct option is '1961.'
Question 10
1 / -0

Taxonomic category of 'Order' comes in between

A
Class and family

B
Kingdom and class

C
Family and genus

D
Phylum and class

Solution

The correct hierarchy of classification with 'order' is given above.
An order is a group of related families which exhibit a few similar characters. For example plant families like Convolvulaceae, Solanaceae are included in the same order polynomials based on the floral characters.
So, the correct option is 'Class and Family'.
