b) mating system or habitat use to diverge
c) reproductive isolation    
d) all of these

d

Which of the following create/s conditions for speciation?
a) polyploidy                       
b) dispersal
c) variance                           
d) all of these

d

 For the process of speciation to continue, which of the following has/have to act on mutations in a way that creates divergence in the isolated populations?
a) natural selection             
b) genetic drift
c) competition     
d) both a and b

d

Explanation: Genetic drift is the change in frequency of an existing gene variant in the population due to random chance


The process of speciation is of……kinds.
a) two    
b) three 
c) four   
d) five

b

Explanation: 1. Sympatric speciation, 2. Allopatric speciation and 3. Parapatric speciation


When population of a species that share the same habitat become reductively isolated from each other, results in the phenomenon of ………speciation.
a) sympatric                       
b) allopatric
c) parapatric                        
d) all of these

a

Sympatric speciation phenomenon most commonly occurs through………
a) euploidy                           
b) polyploidy
c) diploidy                            
d) triploidy

b

Explanation: a tetraploid individual cannot mate with a diploid individual creating reproductive isolation
