Weekly Quiz Competition

Question 1
1 / -0

Closely related morphologically similar, reproductively isolated sympatric populations are designated as

A
Clones

B
Clines

C
Demes

D
Sibling species
Solution
- Clones- They are genetically identical individual produced from the same parent cell.
- Clines- A cline is a gradual change in the phenotypes and genotypes of a species across a geographical gradient.
- Deme- A deme is a locally occurring subset of a population.
- Sibling species- Closely related morphologically similar, reproductively isolated sympatric populations
So, the correct option is 'Sibling species'.
Question 2
1 / -0

Reproduction can occur within members of a

A
Genus

B
Species

C
Family

D
Order
Solution
- Members of a species can interbreed among themselves. In fact, species is defined as the group of individuals who can interbreed among themselves to produce fertile offspring.
- Genus, Family and Order are other higher taxonomic rank which consists of different and several species.
So, the correct option is 'Species'.
Question 3

The surviving members of family hominidae are

A
Homo habilis

B
Homo erectus

C
Homo sapiens

D
All of the above
Solution
Hominidae includes the great apes—that is, the orangutans (genus Pongo), gorillas (Gorilla), and chimpanzees and bonobos as well as human beings (Homo sapiens).
Other members of this family like Homo erectus and Homo habilis are extinct now. They were close relative of modern human beings.
So, the correct option is 'Homo sapiens'.
Question 4

Regarding binomial nomenclature which of the following statement is correct?

A
Both in genus and species the first letter is capital.

B
Both genus and species are printed in italics.

C
Genus and species are always the same name.

D
Genus is written after the species.

Solution

In taxonomy, binomial nomenclature, also known as binary nomenclature, is a formal system of naming species of living things, established by Carolus Linnaeus. Each name is composed of two parts, the Genus, and the species. Most of the time, both of them have a Latin origin and are always printed in italics.
So the correct option is B.
Question 5

So, the correct option is 'Panthera uncia'.
Question 6
1 / -0

Consider the following statements:
Nomenclature for a taxon is necessary because _________.
1. Vernacular names are not universal.
2. Two or more unrelated species are known by the same common name.
3. Vernacular names do not provide information on generic relationship.
4. Vernacular names are not available for all the species.
Which of these statements are correct?

A
1 and 2

B
3 and 4

C
1, 2 and 3

D
1, 2, 3 and 4

Solution

D. 1, 2, 3 and 4
Reason : Neither vernacular names are universally accepted nor available for all the species. The biological facts usually ignored in common name (i.e., no information about generic relationship). Unrelated species also can be known as same common name.
So, the correct answer is option D
Question 7
1 / -0

Operational taxonomic units are used in _________________.

A
Categorizing taxonomic characters

B
Arrangement of herbarium sheets

C

Solution

Operational taxonomic unit is the basic unit in numerical taxonomy. It can be an individual, species, genus, family, order or class.
So, the correct answer is option A.
Question 8

So, the correct answer is '800'.

A
Species by John Ray, Division by Eichler and Phylum by Cuvier

B
Species by Cuvier, Division by Eichler and Phylum by Ray

C
Species by Ray and Phylum and Division by Haeckel

D
Species and Division by Ray and Phylum by Linnaeus
